How to Use the AUTOOL OD720 Oil Extractor and Drainer Step by Step

The AUTOOL OD720 gives a workshop two separate waste-engine-oil paths. It can pull oil through a vehicle-specific extraction probe into its 10 L transparent measuring cup, or collect oil by gravity through its 20 L catch pan. Both paths feed a 70 L storage tank, which is emptied through the drain hose with regulated compressed air. The safest approach is to choose one collection path before setup, keep the engine off, control oil at 40–60°C, monitor both the measuring cup and tank, then use only 0.6–0.8 bar for tank discharge.

Choose the correct OD720 oil-removal path

Service situation	Correct path	Key control
The vehicle procedure permits oil extraction through an identified dipstick or service tube	Vacuum extraction into the measuring cup	Use the correct probe, 6–8 bar supply air and 50–65 cmHg vacuum
The approved sump drain point is accessible under a safely supported vehicle	Gravity draining through the catch pan	Lock the lift and pan position before removing the drain plug
The extraction path is unknown, obstructed or not approved for that engine	Stop and use the vehicle procedure	Never force a probe or guess its depth
Oil is outside the documented 40–60°C range	Correct the condition before collection	Hotter oil can damage components and burn the operator
The measuring cup is near its warning line	Drain it into the storage tank before continuing	The 10 L rating is not a fill target
The storage tank lacks capacity for the planned job	Empty it into an approved receiving container first	Leave headroom below the nominal 70 L capacity

Prepare the vehicle, air supply and waste-oil route

Have the exact vehicle oil-service procedure, approved lift instructions when gravity draining, the correct probe or drain-plug tools, any specified replacement seal, a calibrated torque wrench, gloves, safety goggles and absorbent material. Use clean, regulated shop air capable of the documented 6–8 bar supply range for vacuum generation. Tank emptying needs a separate regulated 0.6–0.8 bar setting, a stable approved waste-oil container and a secured hose route.

Warm the oil only by the vehicle manufacturer’s method, then stop the engine and prevent unintended starting. Keep smoking, sparks and open flames away. Confirm that hot exhaust parts, moving components and electrical connections cannot contact the probe, hose, pan or operator.

AUTOOL OD720 step-by-step procedure

Step 1: Confirm the exact OD720 configuration

Check the model label and locate the 20 L catch pan, height-adjustable lifting rod, 10 L measuring cup, measuring-cup valve, vacuum generator and inlet, gauge, extraction hose and probe holder, tank sight window, tank inlet and safety valves, drain hose, 70 L storage tank, handle and braking casters.

Step 2: Choose vacuum extraction or gravity draining

Use vacuum extraction only when the vehicle procedure identifies a suitable extraction tube and confirms that top-side oil removal is appropriate. Use gravity draining when the sump plug is the approved service point and the vehicle can be lifted and mechanically secured.

Step 3: Confirm the liquid and working temperature

OD720 is for identified waste engine oil within the documented 40–60°C working range. The engine must remain off during operation. Do not extract brake fluid, gasoline, diesel, methanol, ketone, an unidentified liquid or another flammable material.

Step 4: Verify cup, tank and receiving capacity

Read the measuring cup and tank sight level before starting. Estimate the vehicle’s oil quantity and leave headroom in both vessels. The 10 L cup and 70 L tank figures are nominal capacities, not permission to fill to their limits.

Step 5: Inspect every OD720 control and fluid path

Inspect the cup, scale, lid, gauge, measuring-cup valve, vacuum generator, extraction hose, probes, catch pan, lifting rod, tank sight window, valves, check valve, drain hose, fittings, handle and caster brakes. Look for cracks, unreadable levels, loose joints, corrosion, kinks or oil and air leaks.

Step 6: Assemble the cup, rod and catch pan correctly

Rotate the measuring-cup assembly clockwise onto the tank positioning seat, orient it correctly and lock it. Fit the lifting rod and catch pan clockwise, keep the rod vertical, turn the height mechanism counterclockwise to adjust and clockwise to lock.

Step 7: Stabilize the machine and work area

Roll OD720 by its handle, not by the lifting rod, and park it on level floor. Apply the caster brakes. Put on gloves and eye protection, keep the hoses within a controlled area and make sure the operator has a clear exit path.

Step 8: Prepare the vehicle’s extraction access

Follow the vehicle procedure for top-side extraction. Open the oil-filler cap or remove the dipstick only when that procedure calls for it, protect the openings from dirt and identify the approved probe route and depth.

Step 9: Select and connect the correct extraction probe

Choose the vehicle-appropriate probe from the supplied sizes. Check it for damage and connect it securely to the extraction hose. Route the hose without a kink and keep the probe clean before insertion.

Step 10: Close the cup and extraction valves before applying air

Place the measuring-cup valve in its middle slot, which is the closed position. Close the valve on the oil-extraction hose. Confirm that the tank discharge path is not being pressurized and that the cup has enough free capacity.

Step 11: Connect 6–8 bar supply air to the vacuum generator

Connect regulated shop air to the vacuum generator’s air-intake port, then open the air-supply valve. This 6–8 bar supply is for creating vacuum in the measuring cup; it is not the storage-tank discharge pressure.

Step 12: Establish 50–65 cmHg of vacuum

Watch the gauge and adjust the vacuum control until the needle is within the manual’s 50–65 cmHg rated negative-pressure range. Let the reading stabilize and listen for leakage before opening the oil path.

Step 13: Insert the probe to the approved depth

Guide the probe through the identified service tube without bending or forcing it. Stop at the vehicle procedure’s depth; do not use the probe as a dipstick or push it against an internal obstruction.

Step 14: Open the extraction-hose valve and monitor flow

Open the hose valve gradually. Watch oil enter the transparent measuring cup, monitor the gauge and check every joint. Reposition the probe only as allowed by the vehicle procedure. Never leave extraction unattended.

Step 15: Stop extraction and remove the probe cleanly

At the vehicle procedure’s completion condition, close the extraction-hose valve and isolate the air supply. Allow the hose flow to settle, then withdraw the probe slowly while controlling drips. Wipe it and protect the vehicle opening from contamination.

Step 16: Drain the measuring cup into the storage tank

If the cup contains oil, press and rotate its valve into the top-left or top-right open slot. Watch the oil flow into the tank and stop before the tank approaches its safe capacity. After the cup is empty, the manual allows the cup drain path to remain open during unpressurized standby.

Step 17: Lift and mechanically secure the vehicle

Use the approved lifting points, stay within lift capacity and engage every required mechanical lock. Verify stability before anyone or OD720 moves beneath the vehicle. Lower the catch pan for clearance before positioning the machine.

Step 18: Position and lock the catch pan

Roll the machine by its handle, apply the caster brakes, release the rod counterclockwise and raise the pan beneath the drain point. Center it for the initial oil stream as well as the final drip, then lock the rod clockwise without letting the pan support the vehicle.

Step 19: Remove, drain and reinstall the sump plug

Keep your body out of the oil path, remove the plug with the specified tool and monitor the pan, tank level and floor throughout drainage. When the vehicle procedure’s drain condition is met, inspect the plug and threads, fit the specified seal and tighten to the manufacturer’s torque.

Step 20: Lower the pan and complete the vehicle service

Lower and lock the pan, move OD720 clear by its handle, then complete the filter, refill, level and leak checks specified for the vehicle. Restore the filler cap and dipstick and remove the machine before lowering the lift.

Empty the OD720 storage tank

Step 21: Prepare and pressurize the tank at only 0.6–0.8 bar

Secure the drain hose in an approved receiving container with enough free capacity. Close the measuring-cup push-button valve, oil-discharge valve and tank-inlet valve. Connect a separately regulated air supply to the tank inlet, then open the inlet valve and hold discharge pressure within 0.6–0.8 bar.

Step 22: Open slowly, isolate air, depressurize and store

After about five seconds of controlled tank pressurization, open the oil drain valve slowly. Monitor the hose, receiving container, tank and fittings until discharge is complete. Cut off the air supply, close the inlet, fully release retained pressure by the approved procedure, then disconnect air. Clean spills, inspect the cup and hoses, dispose of waste oil lawfully and store OD720 dry with the cup protected and rod lowered.

Troubleshoot OD720 without guessing

If vacuum extraction is slow, close the extraction valve and isolate air before checking oil temperature, probe selection, insertion depth, kinks and the vehicle’s approved access path. If gravity drainage is slow, confirm the oil condition and vehicle drain opening rather than adding vacuum. If tank discharge slows, close the drain valve, isolate air and fully depressurize before checking the hose, receiving-container venting or valve position. A cracked cup, unstable gauge, repeated leak, lifting safety valve or blocked internal path requires qualified service.

What a complete OD720 job looks like

A complete job uses one clearly chosen collection path, identified 40–60°C waste engine oil and an engine that remains off. Vacuum extraction uses the correct probe, a closed cup valve during vacuum generation, 6–8 bar supply air and 50–65 cmHg negative pressure while the cup stays below its warning line. Gravity draining uses a mechanically secured vehicle and a locked, aligned pan. Tank emptying is separate: isolate the measuring cup, secure the receiving hose and use only 0.6–0.8 bar before fully depressurizing the machine.
