Starting the chipper
1. Introduction
Always use your hand to turn the chipper ejecter toud before starting the machine. Turn the
chipper's ejection away from buildings, yourself and other bystanders.
Keep the PTO shaft straight and within 15 degrees horizontally when operating the
chipper.
Drive shaft specifications
• Check that the supplied PTO shaft is the correct length.
• Remember to mount the PTO shaft safety chain.
Security
In the case of those hazards that cannot be effectively eliminated, it is important to
ensure safety.
1. Orient yourself by reading the user manual and safety labels. The machine should only
be used when the tractor's PTO safetyscreen has been installed
Warning and instructions
This, and the upcoming sections, will inform you of the various warnings and instructions for the
hazards associated with the chipper, as well as instructions for proper maintenance and
repairs.
1. Ensure that the safety labels are attached to the chipper, that the user is instructed in the
correct dimensions of the coupling device and the maximum speed for safe use of the chipper.
The drive shaft, like most other components, must be used correctly, this also includes the proper
use of the tractor's safe and secure screens.
Spare parts

3. Safety instructions
Do not operate the chipper until you have read and understood the user manual.
Be sure that the safetyscreen is installed correctly when the chipper is operated. It is important
that the labels are on the chipper and that they are maintained. If your labels have been damaged
and are no longer readable,we are happy to live new ones.
Never leave the chipper lit unattended.
Do not make changes are, repairs or adjustments while the chipper is in progress. Disconnect the
PTO and turn off the engine.
Keep hands, feet , and other body parts away from the chipper.
Turn the ejection spout away from doorways, sidewalks, and other areas where people may reside.
The funnel should be turned with the wind if possible otherwise the tile will blow in your eyes or
down your neck . Neither is particularly comfortable.
Keep everyone, especially children, away from areas where the chipper is being operated. Anyone
who has not read this user manual or received instructions from a qualified person should stay
away from the work area.

5. Checklist
CAUTION: Turn the chipper knife wheel ( Disc ) by hand before connecting it to the tractor to
ensure that it moves sig freely, all bolts are tensioned and that the blades do not hit the sides and
the knife beam.
Make sure that:
1. The PTO shaft is properly lubricated.
2. The PTO shaft is properly lubricated and that the clutch is released when the levers are
pushed against the funnel.
3. The PTO shaft does not break apart or protrude under normal lifting conditions.
4. Check the wood chip pile to see if the blades need to be let go. Longer strips of wood chips are
one of the
the indications that the blades are worn.

6. Using the machine
To function properly, the blades must be sharp. Soil, stones, nails and other foreign material
shorten the life of the blades.
Review the checklist before using the chipper . After checking that there is nothing in the way,
you can start the tractor and lift the chipper until the PTO shaft is within about 20 degrees relative to
the horizontal.
Start the chipper slowly with the PTO engaged and release the PTO coupling slowly. Increase
gradually
the speed until the tractor's PTO speed is 540 RPM.
The material can most easily be fed into the chipper's funnel if the pieces with it
largest end is brought in first.
The pull-in will fold the branches towards the trunk as they are pulled into the funnel. In
summer times, there may be skews in the wood that mean that it must be cut off before the
material can be pulled properly into the machine.
If the material stops in the upholstery, a push at the endn of the wood can help.
ALWAYS REMEMBER to check the material for foreign objects before inserting it into the funnel.
Hydralic information
For models with their own hydraulic station:
• The hydraulic oil must
be level so that it is
visible in the sight glass
• Filling is done by
unscrewing the vent screw
. Viscosity 46 is
recommended
• Possible tightening of the
belts that drive the hydraulic
station
• Oil filter that ensures clean oil
thereby avoiding downtime.
• Should be changed as
needed
For models with hydraulics from the tractor:
• The 2 hoses are connected
to the valve with free
return.

Adjusting the rolling tension – how hard the roller holds the tree. There is 1 handle on each side.
Chipper's knives
IMPORTANT: The machine must be completely turned off and stopped before changing the
blades!
The flywheel and stationary blades must be sharp to get the chipper to do the work as expected.
When the blades have become lethargic, they can be turned 180 degrees as a result of which a
new knife appears. Open to the chipper's flywheel and loosen the 4 bolts that hold the blades and
then turn them over.
Be sure to tighten the mounting bolts of the blades when reinstalling the blades on the flywheel.
The stationary blades are designed with 4 sharp corners. When the corner opposite the
flywheel rounds, the knife is dismantled and another is installed. When installing new blades,
or when changing already existing blades, the blades are set in relation to the counter cutter
found by looking down into the flywheel. The blades should not hit the counter cutter, but
should drive as close to it as possible.
Adjustment of the counter cutter, is done by adjusting the bolts and their associated nut, as
shown in the photo below. These are found under thesv ing wheel, under the machine. Be sure
to re-tighten the bolts and nuts.
Roller speed control
On the left side of the insertion funnel, the roller speed
adjustment is found. 1 = slow - i.e. the chipper cuts the wood
into nicer pieces
10 =fast - ie. the wood chipper cuts the wood into coarser
pieces

handle all lubricants. Store them in an area protected from dust, moisture and other
contaminants.
Lubrication
1. Use a handheld grease sprayer for lubrication.
2. Wipe the grease nipples with a clean cloth before lubrication, to avoid injecting dirt and gravel.
3. Replace and repair broken fittings immediately.
4. If fittings will not take grease, they are thoroughly cleaned.
Service intervals
• The recommended service intervals are based on normal operating conditions. Severe or
unusual circumstances may require more frequent lubrication or oil changes.
