1. Before carrying out any maintenance,

remove the key from the engine Key

Switch to avoid accidental starting and

electrical damage.

2. Regularly inspect the hydraulic fluid. If

contamination particles larger than 20 um

are present, then replace fluid. Good

practice is to replace the hydraulic fluid

every 12 Months to avoid ageing effects.

Note:

The introduction of foreign material into

the hydraulic system can result in poor

performance and repair downtime.

Observe the following practices:

3. When filling or adding oil, always use a

clean funnel with a maximum 60 micron

filter. Ensure that correct fluid is used.

4. Always ensure that hose couplings are

free from dirt before attachment of Tools.

5. All hydraulic hoses should be renewed

every five years.

Notes:

A) Mixing different manufacturers/kinds of

hydraulic oil can cause a chemical

reaction relating to resin or sludge.

Contact the manufacturer for advise to

avoid any problems. In any case, all

traces of the original oil must be removed

by rinsing (washing out) all hydraulic

components.

If filling/draining the Powerig, ensure that

hydraulic fluids are not accidentally

switched.

B) Hydraulic fluids should be disposed of

according to the environmental

guidelines/legislation applicable in the

country where the unit is being maintained

and/or used. Please also consult the

guidelines of your individual oil

manufacturer.

6. Refer to the engine manuals

supplied with this Powerig for

preventative maintenance details.

Adding Hydraulic Fluid

1. Ensure that equipment is readily

available to deal with any spillage of

hydraulic fluid.

2. Remove the screws from the top cover

and remove cover. This will provide better

access to the Filler.

Alternatively, use a short length of flexible

tubing between the funnel and the filler.

3. Before removing the filler cap, use a

clean wipe to remove any accumulated

dirt from the filler cap and surrounding

area. Remove the filler cap.

5. Locate a clean funnel into the filling port

and place an absorbent wipe around the

funnel spout to soak up any excess fluid.

6. Before adding any hydraulic fluid, check

that it is the correct type and grade. (Refer

to page 28).

7. Slowly add the new hydraulic fluid,

pausing regularly to allow fluid in the

funnel to flow into the pump reservoir and

also preventing accidental spillage.

8. Continue to add fluid until it rises to the

top of the Oil Level/Temperature Gauge

glass.

9. Remove the funnel and replace the

filler cap. Ensure filler cap is hand

tightened.

10. Clean any fluid spillage with absorbent

wipes. Replace cover and secure in

place using the screws.
