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 (3), 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 Checking hydraulic oil level
- Open release valve (turn handle knob counter-clockwise) (B) and push ram to its lowest position.
- Remove filler plug.
- Fill the clean hydraulic jack oil. DO not use hydraulic brake fluid.
- Reinstall filler plug.
Lubrication
- Add lubricating oil to all moving parts as needed.
Important: An excess of oil to the volume required may render the hydraulic trolley jack inoperative.
3.5 Only use hydraulic oil, type
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.
4. 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 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.
5. 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).
