Sharpening the saw chain

Sharpen the saw chain when:

• Mealysawdustisproducedwhendampwoodis

cut;

• Thechainpenetratesthewoodwithdifculty,even

whenheavypressureisapplied;

• Thecuttingedgeisobviouslydamaged;

• Thesawpullstotheleftorrightinthewood.

(caused by uneven sharpening of the saw chain or

damage to one side only)

Sharpenthesawchainfrequentlybutalittleeachtime.

Twoorthreestrokeswithaleareusuallysufcientfor

routine resharpening. When the saw chain has been

resharpened several times, have it sharpened in our

authorized service center.

Sharpening criteria:

WARNING: An excessive distance between

the cutting edge and depth gauge increases the

risk of kickback.

►Fig.27: 1. Cutter length 2. Distance between cutting

edge and depth gauge 3. Minimum cutter

length (3 mm)

— Allcutterlengthmustbeequal.Differentcutter

lengths prevent the saw chain from running

smoothly and may cause the saw chain to break.

— Do not sharpen the chain when the cutter length

hasreached3mmorshorter.Thechainmustbe

replaced with new one.

— Thechipthicknessisdeterminedbythedistance

between the depth gauge (round nose) and the

cutting edge.

— Thebestcuttingresultsareobtainedwithfollowing

distance between cutting edge and depth gauge.

• Chainblade91PX:0.65mm

• Chainblade25AP:0.65mm

►Fig.28

— Thesharpeningangleof30°mustbethesameon

all cutters. Different cutter angles cause the chain

to run roughly and unevenly, accelerate wear, and

lead to chain breaks.

— Useasuitableroundlesothatthepropersharp-

ening angle is kept against the teeth.

• Chainblade90PX:55°

File and le guiding

— Useaspecialroundle(optionalaccessory)for

saw chains to sharpen the chain. Normal round

lesarenotsuitable.

• Chainblade90PX:4.5mm

— Sharpentheshortestcutterrst.Thenthelength

of this shortest cutter becomes the standard for all

other cutters on the saw chain.

— Thelecanbeguidedmoreeasilyifaleholder

(optionalaccessory)isemployed.Theleholder

has markings for the correct sharpening angle of

30°(alignthemarkingsparalleltothesawchain)

and limits the depth of penetration (to 4/5 of the

lediameter).

►Fig.30: 1. File holder

— After sharpening the chain, check the height of the

depth gauge using the chain gauge tool (optional

accessory).

►Fig.31

— Removeanyprojectingmaterial,howeversmall,

withaspecialatle(optionalaccessory).

— Round off the front of the depth gauge again.

Cleaning the guide bar

Chips and sawdust will build up in the guide bar groove.

Theymayclogthebargrooveandimpairtheoilow.

Clean out the chips and sawdust every time when you

sharpen or replace the saw chain.

►Fig.32

Cleaning the sprocket cover

Chips and saw dust will accumulate inside of the

sprocket cover. Remove the sprocket cover and saw

chain from the tool then clean the chips and saw dust.

►Fig.33

Cleaning the oil discharge hole

Small dust or particles may be built up in the oil dis-

chargeholeduringoperation.Thesedustorparticles

lubrication on the whole saw chain. When a poor chain

oil delivery occurs at the top of guide bar, clean the oil

discharge hole as follows.

1. Remove the sprocket cover and saw chain from

the tool.

2. Remove the small dust or particles using a slotted

screwdriver with a slender shaft or the like.

4. Remove the battery cartridge from the tool.

Reinstall the sprocket cover and saw chain on the tool.

Replacing the sprocket

CAUTION: A worn sprocket will damage a

new saw chain. Have the sprocket replaced in this

case.
