SAFE WORKING 5
BASIC WOODCHIPPING SAFETY
The operator should be aware of the following points:
MAINTAIN A SAFETY EXCLUSION ZONE around the chipper of at least 10 metres for the
general public or employees without adequate protection. Use hazard tape to identify this
working area and keep it clear from debris build up. Chips should be ejected away from any
area the general public have access to.
HAZARDOUS MATERIAL - Some species of trees and bushes are poisonous. The chipping
action can produce vapour, spray and dust that can irritate the skin. This may lead to
respiratory problems or even cause serious poisoning. Check the material to be chipped before
you start. Avoid confined spaces and use a facemask if necessary.
BE AWARE when the chipper is processing material that is an awkward shape. The material
can move from side to side in the funnel with great force. If the material extends beyond the
funnel, the brash may push you to one side causing danger. Badly twisted brash should be
trimmed before being chipped to avoid thrashing in the feed funnel.
BE AWARE that the chipper can eject chips out of the feed funnel with considerable force.
Always wear full head and face protection.
ALWAYS work on the side of the machine furthest from any local danger, e.g. not road side.
WARNING
The chipper will feed material through on its own. To do this, it relies on
sharp blades on the chipper rotor. To keep the blades sharp, only feed the
machine with clean brushwood. DO NOT put muddy/dirty wood, roots,
potted plants, bricks, stones or metal into the chipper. !
!
OPERATOR'S PERSONAL PROTECTIVE EQUIPMENT REQUIRED
Chainsaw safety helmet
fitted with mesh visor and
recommended ear defenders
to the appropriate
specifications.
Work gloves with
elasticated wrist.
Close fitting heavy-duty
non-snag clothing.
Face mask if
appropriate.
DO NOT
wear rings, bracelets,
watches, jewellery or any
other items that could be
caught in the material and
draw you into the chipper.
Steel toe cap safety boots.

DAILY CHECKS BEFORE STARTING
STARTING TO CHIP
WARNING
Do not use or attempt to start the chipper without the protective guarding
and discharge unit securely in place. Failure to do so may result in
personal injury or loss of life.
!!
CHECK that the chipper is running smoothly.
STAND to one side of the feed funnel.
PROCEED to feed material into the feed funnel.
CHIPPING
Wood up to 100 mm in diameter can be fed into the feed funnel. Enter it into the funnel butt end first.
Release the material before it engages the rotor. Some pieces of wood may move around
significantly while being chipped.
The wood will be drawn into the cutting blade quite quickly, be ready for this to happen. Stand well clear.
A piece of wood which is too tough or too large for the chipper will slow the engine down. When this
happens it is possible to hold back the branches that are being chipped and allow the engine to regain
its speed again.
If a piece of wood gets stuck in the funnel and it cannot be chipped due to its size or shape, it will
need to be removed. Trim the branch until it is a suitable shape for the chipper to accept.
STOPPING THE ENGINE
Move throttle lever to “slow”
Push “on/off” rocker switch position to “off” position.
Close fuel shutoff valve.
For more detailed information refer to the Engine Owner’s Manual

OPERATING INSTRUCTIONS 11
BLOCKAGES
Always be aware that what you are putting into the chipper must come out. If the chips stop coming
out of the discharge tube but the chipper is taking material in - STOP IMMEDIATELY. Continuing to
feed material into a blocked machine may cause damage and will make it difficult to clear.
If the chipper becomes blocked proceed as follows:
STOP the engine and remove the ignition keys.
REMOVE the discharge tube. Check that it is clear.
WEARING gloves, reach into the rotor housing and scoop out the majority of the debris causing
the blockage.
REPLACE the discharge tube.
RESTART the engine and increase to full speed.
ALLOW machine time to clear excess chips still remaining in rotor housing before you
continue feeding brushwood. Feed in a small piece of wood while watching to make sure
that it comes out of the discharge. If this does not clear it, repeat the process and carefully
inspect the discharge tube to find any obstruction.
!!
BLADE WEAR
The most important part of using a wood chipper is keeping the cutter blades sharp. The 18/100G
is fitted with two 17 mm (7") blades. They are 42 mm wide when new.
A new blade should chip between 5 and 10 tonnes of material before sharpening. This figure will be
drastically reduced by feeding the machine with stony, sandy or muddy material.
As the blades become blunt the machine reduces the feed speed. The discharged chips will stop
being so cleanly cut and have more stringy shreds in it. At this point the blades should be sent to a
reputable blade sharpening company. The blades can be sharpened several times during their life.
A wear mark on the reverse side indicates the safe limit of blade wear. Replace when this line is
exceeded.
WARNING
Do not reach into the rotor housing with unprotected hands. There are sharp
blades and any small movement of the rotor may cause serious injury.
NOTE
Continuing to feed the chipper with brushwood once it has become blocked will cause the chipper to
compact the chips in the rotor housing and it will be difficult and time consuming to clear.
AVOID THIS SITUATION - WATCH THE DISCHARGE TUBE AT ALL TIMES.

COPPER EASE SAFETY INFORMATION
The Timberwolf TW 18/100G 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.
