CHECK CHAIN TE NSION

WARNING: Wear protective

gloves when handling c hain. The chain

is sharp and can c ut y ou even when it is

not moving.

Chain t ension is very impor tant . Chain

stretches during use. This is especially

true during the fi rst few times you use your

saw . Always check chain tension each

ti me you use your saw .

1. Unplug unit from the power source.

2. Use a screwdr iver to move chain

around guide bar to ensure kinks do

not exist. The chain should rot ate

freely .

NOTE: It is recommended that the saw

be turned upside down for cha in

tensioning.

3. Loos en bar clamp nuts until they are

finger tight against the bar clamp.

4. Tu rn the adjustin g screw clockwise

until the chain solidly contacts bottom

of guide bar rail . Then, turn adjusting

screw an addit i onal 1/4 tur n. This is

correct chain tension setti ng.

Adjusting Screw -- 1/4 Turn

just ing screw clockwise; to loosen the

5. Check the tension by lifting the chain

fr om the guide bar. Remove some of

the stiffness in the chain by pulling

down and lettin g go of the chain sever-

al times.

6. Continue turni ng the adjusting screw

until the tension is correct (see step 4).

7. Tight en bar clamp nuts with a wrench.

8. Recheck chain tension.

WARNING: If the saw is operated

with a loose chain, the chain could jump

off the g uide b ar and result in serious in-

jury.

CHECK CHAIN SHARPNESS

A sharp c hain makes wood chips. A du ll

chain makes a sawdust powder and

cuts slowly. See

CHAIN SHARPENING in

the

SERVICE AND ADJUSTMENTS

section.

CHECK GUIDE BAR

Conditi ons which requir e guide bar main-

tenance:

S Saw cuts to one side or at an angle.

S Saw has to be forced through the cut.

S Inadequate supply of oil to the bar and

chain.

Check the condition of the guide bar each

ti me the chain is sharpened. A worn guide

bar will damage the chain and make cut-

ti ng diff i cul t .

Aft er each use, wit h unit disconnected

fr om power source, clean all sawdust from

the guid e bar and sprocke t hole.

To maintain guide bar:

S Disconnect the chain saw from the

power source.

S Loosen and remove bar clamp nuts.

Remove bar and chain from saw.

S Clean the oil holes and bar groove af-

ter each 5 hours of operation.

Remove Sawdust From

Guide Bar Groove

Oil Holes

S Burring of guide bar rails is a normal

process of rail wear. Remove these

burrs with a flat file.

S When rail top is uneven, use a flat file

to restore square edges and sides.
