personal injury.
LUBRICATION
All of the bearings in this product are lubricated with a
sufficient amount of high grade lubricant for the life of
the unit under normal operating conditions. Therefore, no
further lubrication is required.
REPLACING THE GUIDE BAR AND CHAIN
See Figures 36 - 45.
DANGER:
Never start the engine before installing the
guide bar, chain, clutch cover, and clutch drum.
Without all these parts in place, the clutch can
fly off or explode, exposing the user to possible
serious injury.
WARNING:
To avoid serious personal injury, read and
understand all the safety instructions in this
section.
Always place the switch in the stop "0" position
Q
before you work on the saw.
Make sure the chain brake is not set by pulling the
Q
chain brake lever/hand guard towards the front
handle to the run position.
NOTE: When replacing the guide bar and chain,
always use the specified bar and chain listed in the
Bar and Chain Combinations section later in this
manual.
Wear gloves when handling the chain and bar. These
Q
components are sharp and may contain burrs.

Remove the bar and chain from the mounting
Q
surface.
Remove the old chain from the bar.
Q
Lay out the new saw chain in a loop and straighten
Q
any kinks. The cutters should face in the direction of
chain rotation. If they face backwards, turn the loop
over.
Place the chain drive links into the bar groove as
Q
shown.
Position the chain so there is a loop at the back of the
Q
bar.
Hold the chain in position on the bar and place the
Q
loop around the sprocket.
Fit the bar flush against the mounting surface so that
Q
the bar studs are in the long slot of the bar.
Replace the clutch cover ensuring that the adjusting

CHAIN MAINTENANCE

See Figures 45 - 47.
Use only a low-kickback chain on this saw. This fast-
cutting chain provides kickback reduction when properly
maintained.
For smooth and fast cutting, maintain the chain properly.
The chain requires sharpening when the wood chips are
small and powdery, the chain must be forced through the
wood during cutting, or the chain cuts to one side. During
maintenance of the chain, consider the following:

Note: Inspect the drive sprocket for wear or damage
when replacing the chain. If signs of wear or damage are
present in the areas indicated, have the drive sprocket
replaced by an authorised service centre.

knob just enough to hold the cover in position.
Replace the clutch cover and tighten up the nut
just enough to hold the clutch cover in place. (For
HCS3335A only)
NOTE: The bar must be free to move for tension
adjustment.
Remove all slack from the chain by rotating the chain
tensioning dial clockwise until the chain seats snugly
against the bar with the drive links in the bar groove.
Lift the tip of the guide bar up to check for sag.
Release the tip of the guide bar and turn the chain
tensioning dial clockwise. Repeat this process until
sag does not exist.
Hold the tip of the guide bar up and tighten the
clutch cover lock knob securely. The chain is correctly
tensioned when there is no sag on the underside of
the guide bar, the chain is snug, but it can be turned
by hand without binding. Ensure that the chain brake
is not set.
Hold the tip of the guide bar up and tighten the clutch
cover nut securely. (For HCS3335A only)
Note: If chain is too tight, it will not rotate. Loosen
the clutch cover lock knob by pressing in and slightly
rotating counter clockwise, then rotate the chain
tensioning dial counter clockwise. Lift the tip of the
guide bar up and retighten the clutch cover lock knob
securely. Ensure that the chain will rotate without
binding.
CAUTION:
Check that the switch is in the STOP "0" position
before you work on the saw.
Improper filing angle of the side plate can increase
the risk of severe kickback.
Raker (depth gauge) clearance.
o Too low increases the potential for kickback.
o Not low enough decreases cutting ability.
If the cutter teeth hit hard objects such as nails and
stones, or are abraded by mud or sand on the wood,
have an authorised service centre sharpen the chain.
