HYDRAULIC POWERPACKS
Changing the Hydraulic Oil
1
Prepare the Machine - Position the machine on
level ground. Switch off the engine and allow it to
cool down.
2
Place a container of suitable size below the
hydraulic tank.
3
Remove the tank drain plug and filler cap to allow
the oil to drain out.
4
Clean and refit the drain plug.
5
Pour hydraulic oil into the tank through the filler
until it reaches the required level in the sight glass.
6
Refit the filler cap.
Note:
Use only the recommended hydraulic oil.
Changing the Main Hydraulic Filter
!
WARNING
Hot oil and engine components can burn you. Make
sure the engine is cool before doing this job.
1
Prepare the Machine - Position the machine on
level ground. Switch off the engine and allow it to
cool down.
2
Place a container of suitable size below the filter to
catch any spilt oil.
3
Remove the bolts securing the lid to the hydraulic
filter housing and remove the lid.
4
Lift out and dispose of the filter.
5
Push the new element firmly into place in the filter
housing.
6
Refit the lid on the filter housing, ensuring that the
spring clip locates between the spigots. Secure
with the bolts.
7
Check the hydraulic oil level.
Refer to
Checking
the Hydraulic Oil Level
.
!
WARNING
There may be limited oil spillage when the filter is
removed. Clean any spillage immediately and
dispose of materials in accordance with current
regulations.
Cleaning the Cooler
The oil cooler fins may be cleaned using low pressure
compressed air. Do not attempt to clean using a wire
brush as this could damage the fins.
Checking the Electrolyte Level
!
WARNING
Battery electrolyte contains sulphuric acid. It can
burn you if it touches your skin or eyes. Wear
safety glasses and handle the battery carefully to
prevent spillage.
1
Prepare the Machine - Position the machine on
level ground. Switch off the engine and allow it to
cool down.
2
Unscrew and remove the battery covers.
3
Look at the level in each cell. The electrolyte
should be 6mm(1/4in) above the plates.
4
Top up if necessary with distilled or de-ionised
water.
5
Refit the battery covers.
Gaining Access to Machine Components
To facilitate easier maintenance, the tubular frame is
fitted with hinge bolts. The frame may be moved to
afford ready access to the machine components in the
following manner:
1
Remove and retain the securing clips.
2
Lift the tubular frame out of the way of the
machine components by hinging it on the bolts.
Note:
It is important that after maintenance, the
tubular frame is restored to its operating position and
that the clips are securely fitted.
Note:
When the machine is to be lifted using the
balanced lifting point, it is important to ensure that the
clips are in place and securely fitted.
Cleaning
It is expected that components will be thoroughly
cleaned and lubricated, where appropiate, also that
any opened hose connections will be blanked to
prevent entry of dirt and excessive loss of hydraulic oil.
Serial Numbers
Serial numbers are stamped on a spacer plate located
between the engine and the hydraulic tank.
