 To Lower The Jack:

 

 

Make sure all personnel are clear, and then open the release screw knob by 

 

turning it counterclockwise. Never open the release screw knob more than two 

 

full turns. The lowering speed can be controlled with the release screw knob by 

 

opening the release knob slightly. 

 
 

 

 

Note: 

Full retraction speed is reached when the release knob is opened two full 

 

turns. Do not open the release screw knob more than two full turns. The jack can 

 

also be lowered in small increments by simply reclosing the release knob at any 

 

time during the jack's descent. 

 

1.4

 

 

Horizontal Application:

 

 

The jack is fully functional when used in a horizontal position as long as the 

 

release knob is facing upward, however the stroke will be limited to 9". The oil 

 

reservoir is not vented and should not leak regardless of the jack's position. 

 

2.1

 

 

Care & Storage: 

 

The Track Jack requires minimal protection from rain, dust, mud or other 

 

potential contaminant's as long as the reservoir fill plug is kept closed and 

 

tight. After using the jack in any particularly dirty application where excess dirt, 

 

mud or grime has built up on the jack, it is recommended the jack be wiped 

 

down prior to storage. The jack should be stored in a clean, dry area and  should 

 

always be stored fully retracted. 

 
 
 
 

2.2

 

 Hydraulic Oil:

 

 

The Track Jack holds approximately 50 cu. in. of oil. The oil should be changed 

 

approximately once a year. SIMPLEX oil Part #AO1, 1 gallon is highly 

 recommended. 
 

 

WARNING: Do not use brake fluid or other non-approved substitute oil: Lighter  

 

weight oils may be used when ambient temperatures are below 32F. 

 

 

 

2.3

 

 

Adding Oil, When Needed: 

 

 A jack that is low on oil will lift a full load but will not extend to its full 9" lift. As the 

 

reservoir runs dry, the lever socket becomes very easy to pump and the jack 

 

stops advancing. To add oil, first fully retract the jack and remove the fill plug. 

 

With the jack in its normal vertical position, fill the reservoir until the oil  

level is 

 

even with the fill hole and replace fill plug. 

 

Note:

 It is important that the oil level is no more or less than even with fill hole. 

 

2.4

 

 Changing The Oil (approximately once a year) 

 

To drain the oil, thoroughly clean the area around the fill plug. Be sure the 

 

jack is fully retracted and remove the fill plug. Lay the jack on its back side and 

 

allow the oil to drain into an appropriate receptacle through the fill plug hole. 

 

Take extra care to make sure no dirt or other contaminant's enter the reservoir 

 

while the fill hole is open. While the reservoir is empty, take the time to inspect
