Maintenance; Checking The Oil Level - SGS TJH1.5 Owner's Manual

MAINTENANCE

PURGING AIR FROM THE TROLLEY JACK
If air becomes trapped inside the hydraulic system of the trolley jack,
the proper working of the trolley jack will be reduced and it may not
fully support the vehicle weight. Air can be purged from the hydraulic
system as follows:
1. Turn the handle anti-clockwise to allow oil to circulate freely around
the system. Remove the filler plug.
2. Pump the handle several times to purge air from the
hydraulic system.
3. Replace the filler plug, then turn the handle clockwise and test the
jack. If efficiency is still low, check the oil level as below.

CHECKING THE OIL LEVEL

If the jack has been stored for long periods, check for oil leaks before
use. If necessary, check the oil level as follows:
1. Ensure the trolley jack is properly lowered by turning the handle
fully anti-clockwise.
2. Remove the oil filler plug on the top of the ram assembly.
A flat-bladed screwdriver will be required.

NOTE:
The oil should be almost level with the bottom of
the oil filler hole. Oil replacement can be
sought by contacting us at SGS Engineering
