IV. Servicing
1. OIL
The oil level should be checked every six months. The total volume of oil is approx.
0.3 litres. Top up the oil in the plastic tank to 5 mm below the maximum level after
first lowering the forks. The following oil types are to be used depending on the
temperature conditions.
Temperature
-5°C – approx. +45° C
-15°C - approx. - 5° C
-25°C – approx. –15°C
NOTE: the properties and quality of the oils conform to standard DIN 51524 (III)-1990
and ISO/CD 11158-1990.
2. To blow off air
When you replace the seals, air can get into the hydraulic oil. This may result in the
forks not rising during the pumping process when the lever is set to "ASCENT". The
air can be removed by setting the control lever to the "LOWER" position and then
moving the handle up and down several times.
3. Daily inspection and servicing
The daily inspection of the unit can limit wear to a large extent. Pay special attention
to the, the axles, the lever, the forks and the up and down control. The forks should
always be unladen and in their lowered position after completing the work.
4. Lubrication
All moving parts should be lubricated at regular intervals with engine oil or grease.
V. Troubleshooting
1) The forks cannot be raise to their maximum height
Too little oil in the tank
2) The forks cannot be raised
No oil in the tank
The oil is contaminated
The outlet valve is maladjusted
Air is getting into the oil
3) The forks cannot be lowered
The rod and the cylinder
are deformed as a result
of the load not having been
balanced several times
Individual parts are deformed as
as a result of the load not having
been balanced
