MAINTENANCE
CHECKING/MAINTAINING THE OIL LEVEL
1. Inspect the hydraulic parts of the
jack for signs of oil leaks. If the oil
needs topping up proceed as
follows.
2. Ensure the jack is fully lowered by
turning the control valve fully anti-
clockwise.
3. Remove the cover plate and the
oil filler plug.
• The oil should be almost level
with the bottom of the filler hole.
• Oil can be topped up using Clarke Hydraulic Oil (Part number
3050830 -1 litre).
4. Bleed any air from the system as described below and replace the filler
plug and cover plate.
5. Dispose of old/spilled oil appropriately and wipe up any spillage. Never
throw away used hydraulic oil with domestic refuse or flush it down a sink or
drain. Collect any hydraulic oil in a leak proof container and take it to your
local waste disposal site.
6. If movement of the main arm becomes sluggish a couple of shots of
grease to the grease nipple will be beneficial.
BLEEDING AIR FROM THE HYDRAULIC RAM
1. Use the operating lever to turn the release valve anti-clockwise, relieving
pressure inside the jack.
2. Pump the operating lever several times to purge air from the hydraulic ram.
3. Turn the release valve clockwise and test the jack. If efficiency is still low,
check the oil level as described above.
4. Wipe up any oil spillage and dispose of old/spilled oil appropriately.
STORAGE
1. Store in a dry place with the ram fully retracted, where it cannot be
damaged by moisture. If stored for long periods, clean any grime from the
piston area before use.
