GENERAL SAFETY PRECAUTIONS
Muffler
The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user.
WARNING! The exhaust fumes from the
!engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material!
In areas with a hot, dry climate there is a high risk of fires. These areas are sometimes subject to government rules requiring among other things the muffler must be equipped with an approved type of spark arrestor screen.
CAUTION! The muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/ or vapours.
WARNING! Never use a saw without a
!muffler, or with a damaged muffler. A damaged muffler may substantially increase the noise level and the fire hazard. Keep fire fighting equipment handy. If a spark arrestor screen is required in your area, never use the saw without or with a broken spark arrestor screen.
Cutting equipment
This section describes how to choose and maintain your cutting equipment in order to:
•Reduce the risk of kickback.
•Reduce the risk of the saw chain breaking or jumping off the bar.
•Obtain optimal cutting performance.
•Extend the life of cutting equipment.
•Avoid increasing vibration levels.
General rules
•Only use cutting equipment recommended by us! See instructions under the heading Technical data.
•Keep the chain’s cutting teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents.
•Maintain the correct depth gauge setting! Follow our instructions and use the recommended depth gauge clearance. Too large a clearance increases the risk of kickback.
•Keep the chain properly tensioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket.
•Keep cutting equipment well lubricated and properly maintained! A poorly lubricated chain is more likely to break and lead to increased wear on the bar, chain and drive sprocket.
Cutting equipment designed to reduce kickback
WARNING! Faulty cutting equipment or the
!wrong combination of bar and saw chain increases the risk of kickback! Only use the bar/saw chain combinations we recommend, and follow the filing instructions. See instructions under the heading Technical data.
The only way to avoid kickback is to make sure that the kickback zone of the bar never touches anything.
By using cutting equipment with
Bar
The smaller the tip radius the lower the chance of kickback.
Chain
A chain is made up of a number of links, which are available in standard and
IMPORTANT! No saw chain design eliminates the danger of kickback.
WARNING! Any contact with a rotating saw
!chain can cause extremely serious injuries.
Some terms that describe the bar and chain
To maintain the safety features of the cutting equipment, you should replace a worn or damaged bar or chain with a bar and chain combinations recommended by Jonsered. See instructions under the heading Technical Data for a list of replacement bar and chain combinations we recommend.
