turn the hydraulic supply circuit control valve “OFF”
before changing the drill steel or rock bit.
COLD WEATHER OPERATION
If the breaker is to be used during cold weather, preheat
the hydraulic fluid at low engine speed. When using the
normally recommended fluid, fluid temperature should
be at or above 50 °F/10 °C (400 ssu/82 centistokes)
before use.
Damage to the hydraulic system or breaker can result
from use with fluid that is too thick.
