Operation
Engaging clutch
Once the engine has warmed up push throttle to full position
(downwards).
Winter operation! Extremely low temperatures require 2-3 minutes
warming up of the engine at idling speed. As a result of the low
temperatures, grease will have stiffened in the system. To overcome
the difficulties arising from this, warm up the engine and lift the
machine several times, then put system into operation by quickly
opening the throttle.
6.3
During operation
Keep breaker dry and clean. Avoid no-load strokes. Never allow the
hammer to run with throttle wide open when forcing away broken or cut
off material or when lifting the hammer. When lifting the hammer, the
engine is decelerated by releasing the gas lever in the handle.
