English (Original Instructions)

PROPER CLOTHING FOR SAFETY

 

Clothing must be sturdy and snug-fitting but allow 

complete freedom of movement. Always wear long 

pants made of heavy material to help protect your 

legs from contact with branches and brush. To reduce 

the risk of cut injuries,wear pants or chaps that 

contain pads of cut retardant material. Never wear 

scarves,ties,jewellery or other items of clothing,which 

might get caught  in the equipment, in brush or on 

branches. Secure hair so it is above shoulder.

 

Wear safety boots with a good tread (with non-slip 

soles). 

 

Wear non-slip, heavy-duty protective gloves. 

 

Wear eye protection with side shields marked to 

comply with EN 166 as well as hearing and head 

protection when operating the product.

REFUELLING (DO NOT SMOKE!)

 

To reduce the risk of fire and burn injury, handle fuel 

with care. It is highly flammable.

 

Mix and store fuel in a container approved for petrol.

 

Mix fuel outdoors where there are no sparks or flames.

 

Select bare ground, stop the engine, and allow it to 

cool before refuelling.

 

Loosen the fuel cap slowly to release pressure and to 

keep fuel from escaping around the cap.

 

Tighten the fuel cap securely after refuelling.

 

Wipe spilled fuel from the unit. Move 9 m away from 

refuelling site before starting engine.

 

Never attempt to burn off spilled fuel under any 

circumstances.

BASIC PRECAUTIONS IN THE CUTTING/WORK AREA

 

Do not stand on any unstable surface while using your 

chainsaw, that includes ladders, scaffolds, trees, etc.

 

Do not start cutting until you have a clear work area, 

secure footing, and a planned retreat path from the 

falling tree.

 

Do not cut from a ladder, this is extremely dangerous.

 

Use extreme caution when cutting small-size brush 

and saplings because slender material may catch the 

saw chain and be whipped toward you or pull you off 

balance.

 

When cutting a limb under tension, be alert for spring-

back so that you will not be struck when the tension in 

the wood fibres is released.

 

Do not operate a chainsaw in a tree unless you have 

been specifically trained to do so.

 

Beware of the emission of exhaust gases, lubricant 

mist and saw dust.

 

This product is very noisy when operating, to prevent 

long term hearing damage, wear hearing protection 

and keep other persons 15 m away from the work 

area. Operating similar tools nearby increases risk of 

injury. Take frequent breaks.

 

Use of hearing protection reduces the ability to hear 

warnings (shouts or alarms). The operator must pay 

extra attention to what is going on in the work area.

 

Keep bystanders and animals out of the work area. Do 

not allow other persons to be nearby during starting or 

cutting with the chainsaw.

NOTE:

 The size of the work area depends on the job being 

performed as well as the size of the tree or work piece 

involved. For example, felling a tree requires a larger work 

area than making other cuts, i.e., bucking cuts etc.

PUSH AND PULL

The reaction force is always opposite to the direction the 

chain is moving. Thus, the operator must be ready to 

control the pull when cutting on the bottom edge of the bar 

and the push when cutting along the top edge. 

NOTE:

 Your chainsaw has been fully factory tested. It is 

normal to find some slight lubricant residue on the saw.

MAINTENANCE PRECAUTIONS

 

Never operate a chainsaw that is damaged, improperly 

adjusted, or is not completely and securely assembled. 

 

Be sure that the saw chain stops moving when the 

throttle control trigger is released. If the saw chain 

moves at idling speed, the carburettor may need 

adjusting. Refer to “Operation-adjusting idling speed” 

later in this manual. If the saw chain still moves at 

idling speed after adjustment has been made, contact 

a service dealer for adjustment and discontinue use 

until the repair is made.

 

Keep the handles dry, clean, and free of lubricant or 

fuel mixture.

 

Follow the sharpening and maintenance instructions 

for the saw chain.

 

Use only the replacement guide bars and low kickback 

chains specified for your saw. You must never modify 

or remove parts from this product or use parts not 

recommended by Ryobi. This will increase the risk of 

injury.

 WARNING

The risk of kickback may increase if non-approved 

guide bar and chain combinations are used. Refer to  

specifications table for qualified replacement guide bar 

and chain combinations.
