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.

SAFE WORKING 6
DO’S AND DON’TS
GENERAL SAFETY MATTERS
DO NOT use chipper unless available light is
sufficient to see clearly.
DO NOT use or attempt to start the chipper
without the feed funnel, belt guard, guards and
discharge unit securely in place.
DO NOT start the chipper running unless properly
guarded.
DO NOT stand directly in front of the feed funnel
when using the chipper. Stand to one side.
DO NOT allow -
DO NOT smoke when
refuelling. Petrol is explosive!
DO NOT let anyone who has not received
instruction operate the machine.
DO NOT climb on the machine at any time.
DO NOT handle material that is partially engaged
in the machine.
DO NOT touch any exposed wiring while
machine is running.
- to enter the machine, as damage is likely.
ALWAYS stop the chipper engine before making
any adjustments, refuelling or cleaning.
ALWAYS check machine has stopped rotating
and remove chipper ignition key before
maintenance of any kind, or whenever the
machine is to be left unattended.
ALWAYS check machine is well supported and
cannot move.
ALWAYS run with the engine set to maximum
speed.
ALWAYS check (visually) for fluid leaks.
ALWAYS take regular breaks. Wearing personal
protective equipment for long periods can be
tiring and hot.
ALWAYS keep hands, feet and clothing out of
feed opening, discharge and moving parts.
ALWAYS use the next piece of material or a push
stick to push in short pieces. Under no
circumstances should you reach into the funnel.
ALWAYS keep the operating area clear of people,
animals and children.
ALWAYS keep the operating area clear from
debris build up.
ALWAYS keep clear of the chip discharge tube.
Foreign objects may be ejected with great force.
ALWAYS ensure protective guarding is in place
before commencing work. Failure to do so may
result in personal injury or loss of life.
ALWAYS use chipper in a well ventilated area -
exhaust fumes are dangerous.

WHEN towing off road ensure inclination is not excessive.
AVOID excessively pot holed ground.
WHEN reversing the chipper the short wheel base will react quickly to steering.
ALWAYS check the discharge is tight before moving.
KEEP tyre pressures inflated to 1.8 bar or 26 psi.
CHECK wheel nuts are tightened to 90Nm or 65 lbs ft.
CLEAR loose chippings and debris from the machine before departing.
ENSURE the feed funnel is closed and the catch is properly engaged before departing.
CHECK the ball head is well greased.
WIND jockey wheel assembly anticlockwise until the tow head is above the height of the ball
hitch on the vehicle.
REVERSE the vehicle so the ball hitch is directly below the tow head.
ATTACH the breakaway cable / secondary coupling to a strong point on the vehicle, not the
ball hitch.
ENSURE the barrel lock is retracted from the tow head.
GRASP handle on tow head and push back catch with thumb.
WIND the jockey wheel assembly clockwise, to lower the tow head onto the ball hitch.
RELEASE handle and continue to wind jockey wheel clockwise. The tow head should snap
into place on the ball hitch. If it doesn't, repeat previous 2 steps.
WIND jockey wheel up until fully retracted and the jockey wheel frame is seated in its notch on
the stem. The chipper weight should be fully on the vehicle.
RELEASE the jockey wheel clamp and slide the jockey wheel assembly fully up.

LOWER the jockey wheel assembly fully.
RETIGHTEN the jockey wheel assembly clamp.
WIND the jockey wheel assembly anticlockwise until it starts to take the weight of the chipper.
GRASP the handle and release the catch with your thumb.
CONTINUE to wind the jockey wheel anticlockwise. This should lift the tow head clear of the ball hitch.
DRIVE the vehicle clear of the chipper.
WIND the jockey wheel assembly to a suitable point where the chipper is level.
THE chipper is now fully detached from the vehicle.
UNHITCHING THE CHIPPER
