Handle blades with extreme caution to avoid injury.•
Gloves should always be worn when handling the
cutter blades.
THE drive belts should be connected while changing•
blades, as this will restrict sudden movement of the
rotor.

Lifting equipment must be used for disassembly.
CLEAN machines are safer and easier to service.•
Avoid contact with hydraulic oil.•
ALWAYS IMMOBILISE THE ENGINE BEFORE UNDERTAKING ANY MAINTENANCE WORK ON THE CHIPPER BY
REMOVING THE KEY AND DISCONNECTING THE BATTERY.
Only fit genuine Timberwolf replacement blades, screws and chipper spares. Failure to do so will result in the
invalidation of the warranty and may result in damage to the chipper, personal injury or even loss of life.
Remove the negative lead first and then the positive1
lead.
Clean, charge and/or top up the battery as required.2
Refitting is the reverse of removal. Apply a smear of3
petroleum jelly to the terminals to prevent corrosion.
The lifting eye is designed to lift the machine’s weight only. Do not use hoist
hook directly on the lifting eye, use a correctly rated safety shackle. Inspect the
lifting eye prior to each use - DO NOT USE LIFTING EYE IF DAMAGED.

The Timberwolf TW 160PH is subject to large vibrations during the normal course of operation. Consequently
there is always a possibility that nuts and bolts will work themselves loose. It is important that periodic
checks are made to ensure the security of all fasteners. Fasteners should be tightened using a torque wrench
to the required torque (see below). Uncalibrated torque wrenches can be inaccurate by as much as 25%. It is
therefore essential that a calibrated torque wrench is used to achieve the tightening torques listed below.
