Confirm t hechain t ension i sinworking order a nd thechain sharp.
Check n ew replaced chain tension d uring operation.
Upon initial operation, new chains c anlengthen considerably. Thecondition ofthechain
influences thecutting performance. Only a sharp chain protects from overload.
Make sure youarewearing thenecessary protective equipment.
Wear s afety g lasses/goggles/visor-safety helmet andhearing protection.
Further protective equipment forhead, hands, legs andfeetishighly recommended.
Adequate protective clothing willreduce p ersonal injury byflying debris o raccidental
contact with sawchain.
Proper functioning oftheautomatic oiler c anbechecked byrunning thechain saw and
pointing thetipofthechain bartowards a piece ofcardboard orpaper o ntheground.
z_ CAUTION:
Do not touch the ground with the chain. Ensure safety clearance
of 20 cm. (7-7/8 inch.) if an increasing oil pattern develops, the automatic oiler is
operating fine. if there is no oil pattern, despite a fuji oil reservoir,
see "Troubleshooting".
KICKBACK (Fig. 10a, 10b)

Kickback Path

_b°,_tdr uctions
KICKBACK is the backward, upward or sudden forward motion of the guide bar occurring
when the saw chain near the upper tip of the guide bar contacts any object such as a log or
branch, or when the wood closes in and pinches chain in the cut. Contacting a foreign object
in the wood can also result in loss of chain saw control.
When kickback occurs the chainsaw reacts unpredictably and can cause severe injuries
to the operator or bystanders. Particular attention must be given when sawing sideward,
slanted or during length cuts, as the spiked bumper usually can not be applied.
To avoid kickback:
* Saw with guide bar at a flat angle.
Never work with a loose, widely stretched or the heavily worn out chain.
Ensure chain is sharpened correctly.
Never saw above shoulder height.
Never work with the tip of the guide bar.
Always hold the chain saw firmly with both hands.
Always use a low kickback chain.
Apply the metal gripping teeth for leverage.
Ensure correct chain tension.

GENERAL CUTTING
Always hold the chain saw firmly with both hands. Front grip with the left hand and rear grip
with the right hand. Fully grip both handles at all times during operation. (See Figs.ll and 12)
Never operate chain saw using only one hand. Ensure power cord is located to the rear,
away from the chain and wood and so positioned that it will not be caught on branches or the
like during cutting. (see THE CHAIN BREAK, page 21)
