6 - ROUTINE MAINTENANCE
This chapter describes routine maintenance, i.e. operations carried out by the operator, on the SPV21 and SPV40 log splitters to keep this in
perfect working order and therefore reliable for continuous, long-term use.
All routine maintenance operations must be carried out with the machine off and in the case of log splitters with electric motor with the
power cable disconnected.
Any other maintenance operation not specifically envisaged in this manual must be carried out by authorised personnel
only in that hazardous situations may arise for which the operator is not prepared.
In the case in which extraordinary maintenance or part replacement operations are not carried out by authorised
personnel, the guarantee shall be immediately null and void and the manufacturer shall be relieved of any responsibility for
injury to persons or animals or damage.
6.1 - How to clean the oil filter
To keep the machine in perfect working order, the oil filter of the hydraulic system must be throughly cleaned every 300 hours of operation.
• Take the back covering which protects the pump off by removing the six screws that block it.
• Unscrew the nut (1) in fig.11
• Remove the gasket (2) which holds the tube with a flat screwdriver by pressing on its periphery (fig.13) until it is out of the tank body.
When the gasket is completely free, extract the tube which supports the filter group.
• Pull the filter (4) off the tube. Be careful not to damage the filter gasket (3 in fig.12).
• Wash the filter with petrol and, if possible, blow it with compressed air. If the cleaning does not succed, the filter must be replaced with
a new one.
• Re-insert the filter in its housing in the oil tank. During this operation, keep the filter leaning on the right.
• Press on the periphery of the gasket with a cross-screwdriver until it has got into the plate (fig.14). Carefully operate according to
fig. 15, otherwise oil may leak.
N.B. In order to re-assemble the gasket easier, we recommend to warm it with a hair dryer before operating.
WARNING:
NEVER USE SHARF SCREWDRIVERS OR CUTTERS TO REMOVE AND RE-ASSEMBLE THE GASKET, OTHERWISE IT COULD BE
DAMAGED.
Once you have re-inserted the tube, fix it with the pertinent nut.
6.2 - How to change the hydraulic oil
The spent oil must be replaced with new oil of the type indicated on page 19 every 600 hours of operation. To change the oil, proceed as
follows.
• Make sure that the mast of the machine is fully retracted (wedge closed).
• Place a receptacle able to hold around 5 litres of oil under the oil drainage plug located to the rear of the machine (fig.16).
• Unscrew the drainage plug with a suitable wrench and let all the oil in the tank drain into the receptacle.
• Once the tank is empty, clean the inlet, the copper washer and the drainage plug with petrol and then replace the drainage plug, drawing
this up tightly. Remember to insert the washer.
The oil tank holds around 4.2 litres of oil.
• Remove the oil plug (fig.3) and fill the tank with the correct oil, pouring in around 3 litres.
• Switch on the log splitter and activate the telescopic mast for 1/3 of its complete travel.
• Lower the wedge completely and add the remaining oil.
Run the machine for two complete cycles to bleed any air from the hydraulic circuit.
• Use the oil rod (fig.3) to check the right quantity of oil.
• Clean the inlet of the oil plug and replace the plug.
I WARNING:
NEVER MIX OIL WITH GENERAL WASTE!
USED OIL MUST BE DISPOSED OF ACCORDING TO CURRENT REGULATIONS IN THE COUNTRY WHERE THE MACHINE IS USED.
6.3 - Sharpening the wedge
After long periods of operation and when required, sharpen the wedge of the log splitter using a fine-toothed file and taking care to remove
any burrs or crushed parts of the metal.
