COLD WEATHER OPERATION
0036
If breaker is to be used during cold weather, preheat hydraulic fluid at low engine speed. When using normally recommended
fluids, fluid temperature should be at or above 50 F (10C) before use.
Good maintenance practices will keep the breaker on the job and increase its service life.
A very important maintenance practice is to keep the hydraulic fluid clean at all times. Contaminated hydraulic fluid causes
rapid wear and/or failure of internal parts.
