CHECK FITTINGS
The Timberwolf TW13/75G 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.

SERVICE INSTRUCTIONS
C190-0187 25.01.2019 Rev: 1.0
SPARES
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.
SAFE LIFTING OF THE CHIPPER
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. Maximum lift weight is
200kg, as
indicated on the machine.
SAFE MAINTENANCE
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.
The major components of this machine are heavy. Lifting •
equipment must be used for disassembly.
Clean machines are safer and easier to service. •
Avoid contact with hazardous materials.•
WARNING
ALWAYS IMMOBILISE THE ENGINE
BEFORE UNDERTAKING ANY
MAINTENANCE WORK ON THE CHIPPER.
ENSURE THE CHIPPER IS STABLE BEFORE
PERFORMING ANY MAINTENANCE.
