Safe operating procedure
Wear safety equipment:
Safety glasses and hearing protection must be
worn at all times
Wear work gloves:
Wearing work gloves is optional but highly
recommended - ensure that the gloves fit tightly
Tie long hair up
Long hair could be pulled into the chipper
Wear clothes that sit tightly
Avoid scarves and any items that can get caught in the chipper
Keep your face and body away from the inlet chute
Stand clear of the discharge zone, even when no material is being fed into the machine
Ensure the exhaust is pointing away from the working area and downwind from the operator and onlookers
Keep proper balance and footing at all times and stand at the same level as the chipper
Do NOT
overreach
Do NOT
run near the machine
Feed only freshly cut material into the chipper
Do NOT
feed in materials covered in gravel, stones and dirt as this can rebound, injure the operator and damage
the machinery
Prune to a size that suits the chipper
’s capabilities
Pre-cut side branches
Branches
will ‘self
-
feed’ more efficiently
Keep the engine clean of debris and other accumulations
This prevents damage to the engine or possible fire
Feed limbs and branches through butt end first, leaving the foliage on
This helps guide the limb down the inlet chute
It reduces spinning and the occurrence of ejection of small pieces back up the inlet chute
Hold larger branches back and feed the chipper with care until you are familiar with its capacity
The engine will slow down or stall if the branch is too large
Feed longer pieces together with short stubby pieces
Feed soft materials intermittently with branches
The wood chips tend to clean out any soft residue left in the chipper
The chipper can clog up with soft, wet or fibrous materials
Keep the outlet free of blockage
If a blockage occurs, turn the engine off, disconnect the spark plug wire and wait for rotor to stop spinning. Open
the outlet chute and remove material until the outlet chute is clear
As the discharge material piles up
Move the chipper to direct the outlet chute away from the pile, or move the processed material
to avoid blocking
Turn off the engine whenever you leave the work area
Run the chipper in an enclosed area
Exhaust fumes contain carbon monoxide, which is poisonous, colourless, odourless, and tasteless
Operate the chipper wearing loose clothing and untied long hair
Stand at a higher level than the base of the chipper when feeding material into it
Process old materials such as dried wooden branches
They get very hard and springy when dried out
They are more awkward to handle
The knives dull much quicker
Feed short, stubby pieces of wood into the chipper
They bounce and spin in the inlet chute
Feed short stubby pieces together with longer pieces
Feed branches that are too large
The chipper can easily stall
