SAFE WORKING

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 both on the feed rollers and 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.

RED SAFETY BAR

Do not rely on the red bar to keep the roller
stationary if it is necessary to clear or touch the
roller. Always switch off the machine and remove
ignition key before approaching the roller.

There are two control boxes, located on either
side of the feed tray.

Roller control boxes- a control box is located on either side of the feed funnel. Their function is to
control the feed roller whilst processing material. They do not control the main rotor.

RED SAFETY BAR = This is the large red bar that surrounds the feed tray and side of the feed funnel.

The bar is spring loaded and connected to a switch that will interrupt the power to the rollers. The
switch is designed so that it only activates if the bar is pushed to the limit of its travel. The rollers stop
instantly, but can be made to turn again by pressing either the GREEN FEED or BLUE REVERSE
control buttons.

MANUAL CONTROLS

WARNING

DO NOT remove, jam, disable, bypass, override or otherwise

impede the effectiveness of the red safety bar.

Control Box Diagram

GREEN BUTTON = Forward feed - Push the button once - this activates the rollers and will allow you

to start chipping (if the rotor speed is high enough).

BLUE BUTTON = Reverse feed - allows you to back material out of the rollers. The rollers will only turn

in reverse as long as you keep pressing the button.

TIMBERWOLF

TW 280TDHB

The engine management unit controls the feed rate of the material going into the chipping chamber. If
the engine speed is below the predetermined level, the engine management unit will not allow the feed
rollers to work in the forward “infeed” direction, until the rotor speed rises above the predetermined
level. At this point, the feed rollers will start turning without warning. The reverse function will work at
any engine speed.

LOCATE the machine on firm level ground.

CHECK machine is well supported and cannot
move.

CHECK jack stand is lowered and secure.

CHECK all guards are fitted and secure.

CHECK the discharge unit is in place and
fastened securely.

CHECK discharge tube is pointing in a safe
direction.

CHECK the feed funnel to ensure no objects
are inside.

CHECK feed tray is in up position - to prevent
people reaching rollers.

CHECK controls as described on page 11.

CHECK (visually) for fluid leaks.

CHECK fuel and hydraulic oil levels.

STARTING TO CHIP

CHIPPING

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

.

Wood up to the recommended diameter can be fed into the feed funnel. Put the butt end in first and
engage it with the feed roller. The hydraulic feed rollers will pull the branch into the machine quite
quickly. Large diameter material will have its feed rate automatically controlled by the engine
management unit.

Sometimes a piece of wood that is a particularly awkward shape is too strong for the feed rollers to
break. This will cause the top roller to either bounce up and down on the wood or both rollers to stall.
If this occurs press the

BLUE REVERSE button until the material has been released. Pull the material

out of the feed funnel and trim it so the chipper can handle it.

Both feed rollers should always turn at the same speed. If one or both rollers stop or suddenly slow
down it may be that a piece of wood has become stuck behind one of the rollers. If this occurs press
the

BLUE REVERSE button and hold for 2 seconds - then repress GREEN FEED button. This should

enable the rollers to free the offending piece of material and continue rotation at the correct speed. If
the rollers continue to stall in the 'forward feed' or 'reverse feed' position push the

RED STOP BUTTON,

turn engine off, remove ignition key and investigate.

OPERATING INSTRUCTIONS

BLADE WEAR

The most important part of using a wood chipper is keeping the cutter blades sharp. Timberwolf
chipper blades are hollow ground to an angle of 40 degrees. When performing daily blade checks
ensure blade edge is sharp and free from chips, if there is any evidence of damage, or the edge is “dull”
change the blade(s). The TW 280TDHB is fitted with 2 blades 158mm (6") long. It is 100 mm wide
when new. A new blade should chip for up to 25 hours before it requires sharpening. This figure will
be drastically reduced by feeding the machine with stony, sandy or muddy material.

As the blade becomes blunt, performance is reduced. With increased stress and load on the machine
the chips will become more irregular and stringy. At this point the blade should be sent to a reputable
blade sharpening company. The blade can be sharpened several times in its life. A wear mark on the
reverse side indicates the safe limit of blade wear. Replace when this line is exceeded.

The machine is also fitted with a static blade (anvil). It is important that the anvil is in good condition
to allow the cutting blades to function efficiently. Performance will be poor, even with sharp cutter
blades, if the anvil is worn.

TIMBERWOLF

TW 280TDHB

OPERATING INSTRUCTIONS

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.
IN the event of heavy blockages the access hatch can be removed (see parts locator on page 3).

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.

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.

BLOCKAGES

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.

This can be viewed through the wall of the tank. Maximum and minimum marks are provided.

SERVICE INSTRUCTIO

NS

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 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.

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.

SAFE MAINTENANCE

BATTERY REMOVAL AND MAINTENANCE

CHECK FITTINGS

SPARES

The Timberwolf TW280TDHB 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

so that pulley is able to slide with minimal wobble.

3. Turn nut in end of tensioner pulley slider until correct belt
tension is achieved. For instructions on checking belt tension
& correct belt tension values, please refer to the Timberwolf
V-Belt Tensioning Data Table at the end of the manual.

5. Re-tighten bolt in centre of tensioner pulley.

6. Run machine and test, recheck belt tension.

7. NOTE: Slack drive belts will cause poor performance and excess
belt and pulley wear.

2

3

NOTE:There will normally be a rapid drop in tension during run-in period for new belts. When new
belts are fitted, check the tension every 2 - 3 hours and adjust until the tension remains constant.

Belt failures due to lack of correct tensioning will not be covered under your Timberwolf warranty.

NOTE: This is a non-adjustable

air breather filter.

WARNING

Use plastic gloves to keep oil off skin and dispose of the used oil
and filter in an ecologically sound way. The oil and filter should be
changed once a year or at any time it becomes contaminated.
Before starting check that the chipper is standing level and brush
away loose chips.

1. Remove the black screw cap from the top of the
filter housing.

2. Partially remove filter element from inner cup.
Leave filter to drain for 15 minutes.

3. Remove filter element from cup when clear of
hydraulic oil.

4. Remove drain plug and drain oil into a suitable
container.

5. Replace drain plug.

6. Refill with VG 32 hydraulic oil until the level is
between the min and max lines on the tank (about

15 litres).

7. Refit the filter cup, install a new filter element and
refit the black screw cap, to the filter housing,
ensuring o-ring remains in place.

CHANGE HYDRAULIC OIL AND FILTER

All the hydraulic hoses should be regularly inspected for chafing and leaks. The hydraulic system is
pressurized to 150 Bar (2175 PSI) and thus the equipment containing it must be kept in good condition.

Identify the hoses that run to the top motor. These have the highest chance of damage as they are
constantly moving. If any hydraulic components are changed new seals should be installed during
reassembly. Fittings should then be retightened.

ETHOD:

1. Set the deflection distance on the lower scale of the tension gauge so that the underside of the 'o'-ring
equals the 'h' value given in the table.

2. Ensure that the deflection force scale is zero'd by pushing the upper 'o'-ring all the way down.

3. Place the tension gauge in the centre of the belt span as shown in the diagram.

4. Press downwards on the rubber buffer, deflecting the belt until the underside of the lower 'o'-ring is level
with the belt behind (use a straight edge if there is only 1 belt).

5

. Take the reading from the deflection scale of the tension meter (read at the lower edge of the 'o'-ring) &

compare this value with that given in the table.

6. Tighten or loosen belts as required following procedure given in this operator's manual.

Tension gauges are available from Timberwolf spares, quoting part no. 18091

TIPS ON BELT TIGHTENING:

There will normally be a rapid drop in tension•
during the run-in period for new belts. When new
belts are fitted, check the tension every 2-3 hours
& adjust until the tension remains constant.

The best tension for V-belt drives is the lowest•
tension at which the belts do not slip or ratchet
under the highest load condition.

Too much tension shortens belt & bearing life.•
Too little tension will affect the performance of•

your machine especially in respect of no-stress
devices.

Ensure that belt drives are kept free of any•
foreign materials.

If a belt slips - tighten it! •
