OPERATING INSTRUCTIONS

BLADE WEAR

The most important part of using a wood chipper is keeping the cutter blades sharp. Timberwolf chipper blades are hollow
ground to an angle of 40 degrees. When performing daily blade checks ensure blade edge is sharp and free from chips, if
there is any evidence of damage, or the edge is "dull" change the blade(s). The TW 280TVGTR is fitted with 2 blades
158mm (6") long. They are 100mm wide when new. A new blade should chip for up to 25 hours before it requires
sharpening. This figure will be drastically reduced by feeding the machine with stony, sandy or muddy material.
As the blade becomes blunt, performance is reduced. With increased stress and load on the machine the chips will become
more irregular and stringy. At this point the blade should be sent to a reputable blade sharpening company. The blade
can be sharpened several times in its life. A wear mark indicates the safe limit of blade wear. Replace when this line is
exceeded.
The machine is also fitted with a static blade (anvil). It is important that the anvil is in good condition to allow the cutting
blades to function efficiently. Performance will be poor even with sharp cutter blades if the anvil is worn.

HYDRAULIC OIL LEVEL AND TEMPERATURE INDICATOR

The indicator is situated on the side of the hydraulic oil tank. The hydraulic oil level should be within the upper and lower
level marks. Refer to filling and draining instructions on page 22.
When the chipper is running, the oil temperature should not
o
exceed 65 C. If it does, stop the machine immediately. Failure
to do so may result in damage. Overheating can result from the
chipper being worked extremely hard in hot conditions, as the
oil is not getting a chance to cool down. Stop the chipper and
allow oil to cool before continuing. If the temperature goes
above 65 o C and the machine is not being worked hard or the air
temperature is not particularly high, this indicates low oil, a jammed
hydraulic motor or valve. Stop immediately and investigate.
When the chipper is on level ground, the oil level should sit
between the red line at the bottom of the gauge and the blue
line at the top. If this level drops significantly it indicates an oil
leak. Stop immediately and investigate.

FUEL LEVEL INDICATOR

The fuel level can be seen through the wall of the plastic tank.

REFUELLING

When refuelling, follow standard Health & Safety practices:
• Stop the engine and allow to cool before refuelling.
• Never smoke or allow naked flames nearby while refuelling.
• Store fuel away from vapour ignition sources such as fires and people smoking.
• Never refuel at operating location, keep a distance of > 10 m to avoid creating fire hazards.
• Fuel storage containers must be approved for appropriate fuel storage and clearly labelled with securely fitting caps.
• Clean area around fuel cap and use a funnel for refuelling. Replace the fuel cap securely. Do not fill the tank beyond
the max. fill indicator.
• Avoid skin contact with fuel. If it gets into eyes wash out with sterile water immediately and seek medical advice as
soon as possible.
• Always clean spillages quickly and change clothes before re-entering the work area if fuel is spilled onto garments.

WINCH OPERATION

Where a winch is factory fitted, it is for recovery purposes only. Always follow the winch manufacturer's instruction manual
provided with the machine. Never winch while an operator is on the driver's platform.
