PRODUCT DESCRIPTION
Hydraulic Truck Jacks are designed to lift, but not support, rated capacity partial vehicle loads consisting of one end
of a vehicle. Immediately after lifting, support loads with a pair of appropriately rated matched jack stands. The 1" Air
Impact Wrench is a hand-held air powered impact wrench designed to be used by one operator for the tightening,
loosening or installing of threaded fasteners.
PREPARATION (Hydraulic Truck Jacks)
Assemble, align and insert the handle assembly and handle position bar into the handle sleeve, then tighten the bolt
on handle sleeve to prevent accidental removal of handle while in use.
Before Use
1. Verify that the product and application are compatible, if in doubt call Omega Technical Service (888) 332-6419.
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. To familiarize yourself with basic operation, locate and turn the release valve (handle knob):
a.
Clockwise
until firm resistance is felt to further turning. This is the ‘
CLOSED
’ release valve position used to
raise
the load.
b.
Counter-clockwise
, no more than 1 full turn from closed position. This is the ‘
OPEN
’ release valve position used
to
lower
the load. The further the release valve is turned counter-clockwise, the faster the load descends.
4. With ram fully lowered, remove the oil filler screw. Check oil level. Proper oil level should be just below the rim of
the opening. Reinstall the oil filler screw.
5. Pour a teaspoon of good quality air tool lubricant into the air supply inlet of the lift control valve. Connect to air
supply, then squeeze the lift control valve for 3 seconds to evenly distribute lubricant.
NOTICE:
These models are equipped with 1/4" NPT air couplers. If installing a different air coupler, ensure thread
tape or compound is used on connections. To ensure dependable, trouble free operation an inline air dryer and oiler
is recommended.
6. Ensure that jack rolls freely. Raise and lower the unloaded ram throughout the lifting range before putting into
service to ensure the jack operates smoothly. Replace worn or damaged parts and assemblies with Omega
authorized replacement parts only.
Bleeding/Venting Trapped Air
1. Open oil filler screw (reference Figure 2, #26).
2. Open release valve.
3. Activate air motor to vent air.
4. Remove set screw (reference Figure 2, #39) and use a screw driver to hold down check ball while very slowly
pumping air motor until oil exiting from screw hole is steady without bubbles.
5. Reinstall set screw approximately two turns into hole (do not fully tighten).
6. Activate air motor a few additional times to vent air, while slowly tightening set screw. Ram should start to raise
as screw is fully tightened.
7. Check oil level and reinstall filler screw (reference Figure 2, #26).
