Annual
Regardless of usage, the Track Jack hydraulic fluid should be changed annually to ensure proper
operation of the jack. To drain the fluid:
1. Thoroughly clean the area around the fill plug.
2. Remove the fill plug and lay the Trak Jack on its back to allow the fluid to drain from the fill hole
into an appropriate receptacle.
•
Dispose of the used hydraulic fluid in accordance with Environmental Protection Agency
regulations.
3. Make sure dirt or other contaminants do not enter the reservoir while the fill plug is removed.
When drained, check the fluid for contaminants. If the fluid appears gritty or dirty, flush the
reservoir with clean hydraulic fluid before refilling.
4. Refill the reservoir with the recommended hydraulic fluid. Stand the jack upright, and with the
piston fully retracted, fill the reservoir until the fluid level is 1/8 inch below the bottom of the fill
plug.
5. Before returning the jack to service, fully extend the piston without a load by pumping the pump
handle without the long extension handle. If the fluid level is correct, the pump handle will become
almost impossible to pump by hand as the piston reaches full extension. Replace the plug.
6. It may be necessary to bleed air out of the cylinder. See instructions for
Purging Air
.
7. Inspect the jack for leaks, cracks, or other damage.
Purging Air
Air trapped within the jack hydraulic system can be removed by performing the following steps.
1. Make sure the plunger is fully retracted.
2. Pry out the cap on top of the unit.
3. Loosen (
do not remove
) the cap screw under the cap located in the top of the plunger.
4. Place the jack in a suitable fixture to prevent the extension of the plunger while purging air.
5. Add hydraulic fluid to the reservoir if necessary. See instructions above for adding fluid.
6. Pump the handle until oil comes up through the thread area of the cap screw in the plunger.
7. Tighten the socket head capscrew to 10-12 ft. lbs./14-16 Nm.
8. Top off the reservoir with hydraulic fluid.
Note:
Make sure the plunger is fully retracted before filling the reservoir.
