3. Fill with new oil through the oil fill hole.
Cleanliness is important – do not allow
any dirt or foreign matter to get into the
oil through the oil fill hole. Fill with oil
until it is just under the lower edge of the
oil fill hole. Replace the oil fill plug.
4. Bleed the hydraulic system according to
the instructions below.
LUBRICATION
1. Lubricate all moving parts with thin oil or
a suitable spray lubricant when necessary.
2. For light duty and infrequent use,
lubricate every 6 months.
3. For heavy duty and frequent/daily use,
lubricate every month.
CORROSION PREVENTION
1. Check the lift and pump pistons on
the cylinder unit every two months
(more frequently if used in demanding
conditions) for signs of rust or corrosion.
Raise the saddle as high as it goes and
inspect under and behind the lift arm.
Remove any rust and spray with WD-40
(or equivalent) or apply a light coat of oil
to prevent rusting.
2. When putting the jack into storage,
ensure the saddle and pump piston are in
their lowest position.
Only use high grade hydraulic oil. Do not use
brake fluid, alcohol, glycerin, detergent, motor
oil or dirty oil. Use of a non-recommended
hydraulic fluid can cause damage to the jack.
BLEEDING
Air in the hydraulic system can impair performance.
If air has entered the hydraulic system, it must
be removed as instructed below.
1. Open the release valve all the way by
turning the handle anticlockwise as far as
it will go.
2. Pump the handle rapidly several times.
3. Close the release valve by turning the
handle clockwise.
4. Pump the handle until the lift arm
reaches maximum height. Pump a few
more times to drive out any air.
5. Open the release valve all the way by
turning the handle anticlockwise as far
as it will go, to lower the saddle to its
lowest position. Press the saddle down if
necessary.
6. Turn the relief valve clockwise to closed
position and function test the jack.
Repeat the above steps if necessary to bleed it
more.
