Inspection, Maintenance, & Cleaning

Procedures not specifically explained in this 

manual must be performed only by a 

qualified technician.

To prevent serious injury from tool failure: 

Do not use damaged equipment.  

If abnormal noise or vibration occurs, have 

the problem corrected before further use.

1. 

BEFORE EACH USE,

 inspect the general condition 

of the Bottle Jack.  Check for loose screws, 

misalignment or binding of moving parts, cracked 

or broken parts, damaged Air Hose, and any other 

condition that may affect its safe operation.

2. 

AFTER USE,

 clean external surfaces of the 

Bottle Jack with a clean, moist cloth and a 

mild detergent.  Do not use solvents.

Bleeding Instructions

Before each use or if Bottle Jack performance decreases,  

check for excessive air and proper hydraulic oil 

level in Bottle Jack. If Jack appears not to be 

working properly, it may be necessary to purge its 

hydraulic system of excessive air as follows:

1.  Turn Knob (6.11) Assembly completely clockwise, 

closing the Release Valve Screw (3.21). 

Pump the handle up and down quickly 5-6 times.  

Then turn the Knob (6.11) 1-1/2 turns 

counterclockwise, releasing pressure.

2.  Remove the Filler Plug (1.19), and fill the Cylinder 

Base (1.14) reservoir with hydraulic oil (not included).

3.  Rapidly pump Handle several times to purge air.

4.  Turn Knob (6.11) clockwise until 

snug to hold pressure.

5.  Top off the reservoir with hydraulic oil.  

Then replace the Filler Plug (1.19).

IMPORTANT:  After bleeding the Bottle Jack, test the 

Jack for proper operation prior to its actual use.

NOTE:  

To prevent damage to the Bottle Jack, check 

for excessive air and/or low hydraulic oil regularly.

6. 

WHEN STORING, 

turn Lock Lever (6.5) 

to its open position (counterclockwise).  

Always

 

store the Bottle Jack and its accessories 

in a clean, dry, safe location out of reach of 

children and other unauthorized people.

TO PREVENT SERIOUS INJURY AND DEATH:  

Use caution when troubleshooting a malfunctioning jack.  

Stay well clear of the supported load. Completely 

resolve all problems before use.  If the solutions 

presented in the Troubleshooting guide do not 

solve the problem, have a qualified technician 

inspect and repair the jack before use.
After the jack is repaired:  Test it carefully 

without a load by raising and lowering it fully, 

checking for proper operation, BEFORE 

RETURNING THE JACK TO OPERATION.
