CHAIN LUBRICANT
Proper lubrication of the chain while in operation
reduces friction between the chain and the guide
bar to a minimum and assures a longer service life.
• Use bar and chain oil of high quality for this
purpose.
• Do not use used or reclaimed oil to avoid various
oiler problems.
• Use ECHO bar and chain oil.
• When ECHO bar and chain oil is not available:
Use motor oil, etc.
• Use bar and chain oil of the following grades:
SAE No. 30 ....... in summer
SAE No. 10 ....... in winter or when cutting
• When refueling, also refill chain oil.
• After choke control knob is pulled and then
knob is returned to original position,
throttle remains a little open (latch
condition).
• If engine is started in this latch condition,
chain starts to turn. Do not start engine
before chain brake is locked.
• After starting the engine, squeeze throttle
trigger slightly to release throttle latch and
pull front hand guard towards the operator
immediately.
(Chain brake unlocked position)
• Never use throttle latch for cutting.
• Use the chain brake only in starting or in
emergencies.
