Before Use
1. Verify that the product and application are compatible, if in doubt call Matco Tools Technical Service (866) BUY-
TOOL.
2. Before using this product, read the operator's manual completely and familiarize yourself thoroughly with the
product, its components and recognize the hazards associated with its use.
3. Assemble handle, ensure spring clips align with slots.
4. To familiarize yourself with basic operation, use the notched end of provided handle to engage and turn the release
valve:
a. Clockwise until firm resistance is felt to further turning. This is the 'cLOSed' release valve position used to
raise the ram plunger.
b. Counter-clockwise, but no more than 1/2 turn from the closed position. This is the 'OPen' release valve
position used to lower the ram plunger.
5. With ram plunger fully retracted and release valve closed, pump the operating handle. If ram plunger responds
immediately, jack is ready for use. If jack does not respond, follow Bleeding/venting trapped air instruction below.
6. Check that the pump operates smoothly and that the extension screw will thread up/down easily before putting into
service. Replace worn or damaged parts and assemblies with Matco Tools authorized replacement parts only.
Bleeding/venting trapped air
With the release valve in the OPEN position (step 4b above) and with ram plunger fully lowered, locate and remove
the oil filler plug. Insert the pump handle into the handle sleeve; then pump 6 to 8 full strokes. This will help release
any pressurized air which may be trapped within the reservoir. Oil level should be even with the bottom of the oil
filler hole. Reinstall the oil filler plug.
