SAFE LIFTING & SECURING DOWN 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
1350kg, as indicated on the machine.
BATTERY REMOVAL AND MAINTENANCE
CHECK FITTINGS
The Timberwolf TW 230VTR 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.
WARNING
REFER TO THE BATTERY SAFETY SECTION
ON PAGES 18.
SAFE MAINTENANCE
WARNING
ALWAYS IMMOBILISE THE ENGINE BEFORE
UNDERTAKING ANY MAINTENANCE WORK
ON THE CHIPPER BY REMOVING THE KEY
AND DISCONNECTING THE BATTERY.
ENSURE THE CHIPPER IS STABLE BEFORE
PERFORMING ANY 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.•
The method of securing the chipper can vary
depending on the type of carrier and position of
tie down points available on the carrier.
Timberwolf recommend where possible to secure
machine to carrier using correctly rated ratchet
straps directly lashing from 4 points on the inner
(a) or outer (b) track frame and over the tracks to
the carrier lashing points as shown.
Securing a Timberwolf chipper ready for
transport must be carried out by competent
qualified personnel. Failure to observe this
procedure could result in chassis and/or
undercarriage damage.

(minimum) ratchet strap
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.
