Chain Saw Safety Manual

English

6

Never cut several limbs at once.

Do not overreach.

Never cut above shoulder height.

Use extreme caution when re-

entering a previous cut.

Do not attempt plunge cuts if you 

are not experience in this cutting 

technique.

Be alert for shifting of the log or 

other forces that may cause the cut 

to close and pinch the chain.

Always cut with a correctly 

sharpened, properly tensioned 

chain – the depth gauge setting 

must not be too large.

Use a low kickback chain and a 

narrow radius guide bar.

Pull-in (A)

Pull-in occurs when the chain on the 

bottom of the bar is suddenly pinched, 

caught or encounters a foreign object in 

the wood. The reaction of the chain pulls 

the saw forward – always hold the 

spiked bumper securely against the tree 

or limb.

Pushback (B)

Pushback occurs when the chain on the 

top of the bar is suddenly pinched, 

caught or encounters a foreign object in 

the wood. The reaction of the chain 

drives the saw straight back toward the 

operator. To avoid pushback.

Be alert to situations that may cause 

the top of the guide bar to be 

pinched

Do not twist the guide bar in the cut.

Exercise extreme caution

with leaners

with trees that have fallen 

unfavorably between other trees 

and are under strain

when working in blowdown areas.

Do not work with the chainsaw in such 

circumstances. Use block and tackle, 

cable winch or tractor.
Pull out exposed and cleared logs. 

Select clear area for cutting.
Deadwood (dry, decayed or rotted 

wood) represents a considerable risk 

that is difficult to assess. Identifying the 

extent of the dangers is complicated, if 

not impossible. Use aids such as a cable 

winch or tractor in such cases.

When felling in the vicinity of roads, 

railways, power lines, etc., take extra 

precautions. If necessary, inform the 

police, utility company or railway 

authority.

Cutting

Do not operate your saw with the 

starting throttle lock engaged. Engine 

speed cannot be controlled with the 

throttle trigger in this position.
Work calmly and carefully – in daylight 

conditions and only when visibility is 

good. Ensure you do not endanger 

others – stay alert at all times.
Use the shortest possible guide bar: The 

chain, guide bar and chain sprocket 

must match each other and your saw.

Position the saw so that your body is 

clear of the cutting attachment.
Always pull the saw out of the cut with 

the chain running.
Use your chain saw for cutting only. It is 

not designed for prying or shoveling 

away limbs, roots or other objects.
Do not underbuck freely hanging limbs.
