3.4 Check and Refill Oil
(a) Remove hydraulic unit cover, if cover is provided.
(b) With jack in the fully lowered and level position, remove oil filler plug.
(c) Proper oil level should be just covering inner cylinder as seen from the oil filler plug hole.
(d) Do not overfill. Always fill with new, clean hydraulic jack oil as recommended above.
(e) Reinstall oil filler plug. Then reinstall unit cover.
3.5 Only use hydraulic oil, type ISO VG22.
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 jackin
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 foreign 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
