MAINTENANCE FOR THE
MODEL 210-3, -4, -5 SRA
•
It is highly recommended that the concrete dust on the drill unit be
cleaned off daily to prevent it from hardening.
•
The drill unit should be stored with the drills in the vertical position.
•
For longer storage periods, flush the drill motors with a substance
that will prevent rust from forming due to moisture in the drills. Any
amount of rust can cause the cycling valve to seize. If this happens,
the drill motor generally has to be taken apart and cleaned
thoroughly before it will operate. Substances such rock drill oil,
Marvel Mystery Oil, or even diesel fuel can be used to flush the drill
motors.
