To Refill with Oil
Remove the filler plug and with the saddle DOWN put InAW-32 Light Hydraulic Oil (or oil that meets
MIL•F•17111 011 specifications) until the level comes up to within 1/4" to 3/8" below filler hole. Overfilling
will cause oil to spurt out the vent hole as the Jack Is lowered, or may' prevent jack from lowering properly.
Insufficient oil will cause the Jack to 11ft only part way. Always be sure to put in oil only when the saddle is
all the way down. Be careful not to let any dirt get into the reservoir while the Filler Plug Is out.
Do not use
brake fluid, transmission fluid or any other fluids—doing so could damage the seals and cause jack
failure.
Overload Protection
The Lowering Valve (Release Valve) is also designed to work as an overload protection device. If you attempt
to raise a load that exceeds the jack’s rated capacity, this valve will automatically release the cylinder pressure
as an overload protection safety feature.
Safety Precautions
Follow OSHA Standards and ASME PALD Part 10 Instructions. Never exceed the Jack’s rated load capacity.
Only lift vehicles at the recommended lift points found in the vehicle’s service manual. Eye protection should
be worn per OSHA recommendations. Always use the Jack on smooth, hard and level surfaces – while
keeping the load centered on the saddle. Always check the Jack prior to each use – do not attempt to use the
Jack if any defect is observed. Do not add accessories or modify the Jack in any way. Always use Jack Stands
under the vehicle and stay clear when lifting or lowering the vehicle.
Preventive Maintenance
1. Inspect the jack before each use. Take corrective action before using the jack is a leak or defect is found.
2. Keep all working parts thoroughly lubricated. Keep Jack clean. Dirt is the major cause of Jack failure, and
all openings should be kept free of debris.
3. Packing nuts at the piston and pump plunger should be kept moderately tight. These Packings are
NOT
under high pressure, and should only be tight enough to prevent leakage.
4. Keep oil filled to within 1/4” to 3/8” of fill opening. Replace oil at least once a year.
5. Ball Valve may be removed for Inspection and cleaning by removing the Ball Chamber Plug [V] and using
a small magnet, remove the balls [X&Z] and the ball weight[Y]. See Diagram
IMPORTANT
: Whenever it is necessary to loosen or remove the Ball Chamber Plug, the Gasket [W] should
be replaced with a new one. Oil leakage at this point is usually caused by trying to reuse an old gasket over
again.
