3 MAINTENANCE (§ 7.1.3 de l'EN 1494+A1)
Important: Both the maintenance and repair of the hydraulic trolley jack may only be performed by qualified persons, who have sufficient knowledge of
the hydraulic systems used in these devices as a result of their training and experience.
3.1 Keep the hydraulic trolley jack clean and lubricate all moving parts at regular intervals (5), which must be clean and protected from aggressive conditions at all times.
3.2 Only original spare parts should be used.
3.3 Prior to each use, check for bent, broken, cracked or loose parts and solve the problem, if appropriate. If it is suspected that the hydraulic trolley jack has
been subjected to abnormal loads or has suffered any knocks, withdraw it from service until the problem has been rectified.
3.4 If the oil level needs to be checked or refilled, With saddle fully lowered, set hydraulic trolley jack in its upright, level position. Locate and remove oil filler
plug. Fill with oil even with the bottom of oil filler plug hole. Reinstall the oil filler plug.
The parts table alongside shows the volume of oil required.
Make sure that no dirt enters with the new oil.
Following a period of prolonged intensive use, it is recommendable to change the oil in order to extend the useful life of the hydraulic trolley jack.
With saddle fully lowered, remove the oil filler plug. Lay the hydraulic trolley jack on its side and drain the fluid into a suitable container. Fill with oil even
with the bottom of oil filler plug hole. Reinstall the oil filler plug.
Important: An excess of oil to the volume required may render the hydraulic trolley jack inoperative.
3.5 Only use hydraulic oil, type ISO VG 13.
Extremely Important: Never use brake fluid.
3.6 When the hydraulic trolley jack is not in use, make sure the lifting arm is fully retracted to avoid corrosion.
Apply an anti-corrosion product to the pistons, if appropriate.
3.7 Keep the hydraulic trolley jack in a clean, dry place and out of children reach.
3.8 At the end of the useful life of the hydraulic trolley jack, drain off the oil and hand it over to an authorised agent and dispose of the hydraulic trolley jack in
accordance with local regulations.
3.9 Both the repair kit, which exclusively contains the o-rings and seals of the hydraulic trolley jack, and the spare part sets must be ordered using the
reference assigned in the table.

PREVENTIVE MAINTENANCE

Important: The greatest single cause of failure in hydraulic units is dirt. Keep the service hydraulic trolley jack clean and well lubricated to prevent fo-
reign matter from entering the system. If the hydraulic trolley jack has been exposed to rain, snow, sand, or grit, it must be cleaned before it is used.
4.1 Store the hydraulic trolley jack in a well protected area where it will not be exposed to corrosive vapors, abrasive dust, or any other harmful elements.
4.2 Regularly lubrificate the moving parts in the wheels, arm, handle, and pump roller pin.
4.3 Replace the hydraulic fluid in the reservoir at least once per year. To check the hydraulic fluid level, lower the lifting arm completely. Remove the rubber
filler plug from the power unit. The hydraulic fluid level shoulb be at the bottom of the filler plug hole. If necessary, add hydraulic fluid and install the filler
plug.
IMPORTANT : the use of alcohol or hydraulic brake fluid could damage the seals and result in hydraulic trolley jack failure.
4.4 Inspect the hydraulic trolley jack before each use. Take corrective action if any of the following problems are found;
a. Cracked, damaged housing
b. Excessive wear, bending, or other damage
c. Leaking hydraulic fluid
d. Scored, damaged piston rod
4.5 Keep warning labels and instructional decals clean and readable. Use a mild soap solution to wash external surfaces of the hydraulic trolley jack.

TROUBLESHOOTING GUIDE

Repair procedures must be performed in a dirt-free environment by qualified personnel who are familiar with this equipment.
CAUTION : To prevent personal injury, all inspection, maintenance, and repair procedures must be performed when the hydraulic trolley jack is free
of a load (not in use).
Trouble
Hydraulic trolley jack will not
lift load
The load slowly and unintentio-
nally lowers after lifting
While lowering, fluid leaks from
reservoir area.
Hydraulic trolley jack saddle
will not descend to lowest
advertised height
Ram pluger will not remain
lowered after released from
contact with load (creeps back
up)
Poor lift performance
Hydraulic trolley jack no lift to
full extension
GUARANTEE
Type D = 2 years. See the general conditions in the FACOM catalogue or the FACOM price list.

Cause
1 . Release valve not tightly closed.
2. Load is too heavy.
1. Hydraulic unit malfunction.
1. Reservoir overfilled.
2. Ram pluger/ cylinder deformed, seized up in
ram cylinder and/or top nut, likely the result of
off-center loading.
1. Air trapped in system.
1. Fluid level low.
2. Air trapped in system.
3. Hydraulic unit malfunction.
1. Fluid level level low.
e. Loose hardware
f. Modified or altered equipment
1. Ensure release valve is closed. Use the provided handle to engage
the release valve. Turn the release valve clockwise until firm
resistance is felt.
2. Consider higher capacity hydraulic trolley jack.
1. Contact customer support.
1. Drain fluid to proper level.
2. Contact customer support.
1. If there is no longer contact between the lifted load and the jack
saddle, simply remove the hydraulic trolley jack and follow the
Owners Manual maintenance Instructions for bleeding air from sys-
tem. However, if there is any loaded contact between the saddle and
the vehicle, STOP, use another jack to raise the load high enough to
re-install jack stands. Remove the affected hydraulic trolley jack, then
the stands. Using the other jack, lower the load by turning the release
valve counter-clockwise, but never more than 1/2 full turn, then follow
the Owners Manual Maintenance instructions for bleeding air from
system.
1. Ensure proper fluid level.
2. Carrefully follow the Owners Manual Instructions for bleeding/
venting the hydraulic trolley jack.
3. Contact Customer Support.
1. Ensure proper fluid level.
