[11] Warm-up of machine prior to operation
- Do not operate the machine right after starting the engine. Idle the machine for warm-up. Warm the
hydraulic oil sufficiently especially in winter or in the cold place.
- Especially in winter, the carrier’s engine should be warmed up for 5 to 10 minutes 30~40℃(86∼105℉)
before breaker operation.
- When operating the hydraulic breaker, idle the engine and operate the hydraulic breaker with a light
load.
[12] Stop operation when hoses are vibrating abnormally.
Check the hoses on the high pressure and low pressure sides of the breaker for abnormal vibration. If
they are vibrating abnormally, contact the nearest Soosan dealer.
[13] Avoid blank hammering.
Blank hammering accelerates wear and tear on breaker and carrier components and may result in
failure of one or more components. Excessive blank hammering may be considered equipment abuse
and may result in voiding warranties. In case of blank hammering, hammering sound changes.
[14] Operate the breaker at proper engine speed.
Break rocks at the specified engine speed. Raising engine speed more than necessary does not
strengthen hammering force but increase oil temperature to the detriment of piston and valve.
