MAINTENANCE
Important: Inspect this equipment regularly and check for damage before use.
• Never use this equipment if any damage or fault is detected. Immediately repair or replace damaged parts.
• Only use Tundra Industrial approved replacement parts when repairing the jack.
• The use of unapproved parts may be dangerous and will invalidate your warranty.
• Do not use brake uid or any uid other than hydraulic jack uid, as to do so may cause serious damage to the jack and will invalidate the
warranty.
• Periodically check the pump piston and piston rod for signs of corrosion. Clean exposed areas with a clean oiled cloth.
Storage:
When the jack is not in use, the ram and piston must be placed in their lowest positions to minimise corrosion.
Lubrication:
Remove the handle to render the jack inoperable and store in a secure dry environment.
Keep the jack clean and lubricate all moving parts with acid free oil on a regular basis.
Checking Hydraulic Oil Level / Refilling Oil:
1. Fully lower the jack.
2. Remove the ller plug.
3. The correct oil level is indicated to the bottom of the ller opening.
4. We recommend that you should replace the hydraulic oil after every year of extensive use. Drain the oil through the ller plug opening.
5. Ensure that no dirt or debris is allowed to enter the jack or the fresh oil during this process.
6. To replace the oil ll as required.
7. Pump (the unloaded jack) 5 or 6 times to expel any excess air.
8. Pump jack to full height and pour off excess oil before retting the ller plug.
Note: Ensure waste oil is disposed of in accordance with local authority regulations.
De-commissioning:
Draw off the oil into an approved container and dispose of the jack and the oil according to local regulations.
