PREVENTIVE MAINTENANCE

Important: Dirt is the greatest single cause of failure in hydraulic units. Keep the jack clean and well lubricated to prevent foreign matter from
entering the system. If the jack has been exposed to rain, snow, sand, or grit, it must be cleaned before it is used. The use of alcohol, hydraulic
brake fluid, detergent motor oil, or transmission oil could damage the seals and result in jack failure. Use only approved hydraulic fluid (type HL
or HM) with an ISO grade cinematic viscosity of 30 cSt at 40°C or an Engler viscosity of 3 at 50° C.
1. When the jack is not is use, keep the piston and pump rods fully retracted. Store the jack on its base (in an upright position) and in a well protected area
where it will not be exposed to corrosive vapors, abrasive dust, or any other harmful elements.
2. Visually inspect the jack before each use. Take corrective action if any of the following problems are found:
a. Cracked or damaged housing
b. Excessive wear, bending, or other damage
c. Leaking hydraulic fluid
d. Scored or damaged piston rod

TROUBLESHOOTING GUIDE

Repair procedures must be performed in a dirt-free environment by qualified personnel who are familiar with this equipment.
Trouble

Ram advances slowly
Ram advances but doesn't
hold pressure
Jack leaks oil
Ram will not retract, or
retracts slowly
GUARANTEE
Type D = 2 years. See the general conditions in the FACOM catalogue or the FACOM price list.

Cause
1 . Air in system.
2. Viscosity of oil too high.
3. Ram sticking or binding.
4. lnternal leakage in ram.
1 . Release valve is open.
2. Law/no oil in reservoir.
3. Air locked system.
4. Load is above capacity of system.
1. Law oil level in reservoir.
2. Piston rod is binding.
1. Pump not working correctly .
2. Leaking seals.
1. Pump check valve not working.
2. Ram seals are leaking.
1. Worn or damaged seals.
1. Release valve is closed.
2. Reservoir too full.
3. Ram damaged internally.
e. lncorrectly functioning swivel heads or adj. screw
f. Loose hardware
g. Modified or altered equipment
1. With jack sitting on its base and ram retracted, bleed air from
unit. See back of page 1 of 1 to bleed air from the system.
2. Change to a lower viscosity oil.
3. Look for dirt, gummy deposits, leaks, misalignment, worn
parts, or defective packing.
4. Take jack to authorized service center for repair.
1. Close release valve.
2. Fill with oil to fill line & bleed system.
3. Bleed the system.
4. Use correct equipment.
1. Fill with oil to fill line & bleed system.
2. Look for dirt, gummy deposits, leaks, misalignment, worn
parts, or defective packing.
1. Take jack to authorized service center for pump repair.
2. See spare parts.
1. Take jack to authorized service center for seal replacement.
2. See spare parts.
1. See spare parts.
1. Open release valve.
2. Drain oil to correct level.
3. Take jack to authorized service center for repair.
