Greasing the Bit
Service Interval/Specification
Grease the bit before each use and then after every 1
to 2 hours of operation. Grease it immediately after
washing.
Grease Type: General-purpose grease, certified NGLI
number 1 or 2.
How to Grease
1.
Tilt the breaker so that it is vertical, then lower it
to the ground so that the bit is pushed up into the
breaker as far as possible.
IMPORTANT: Failure to push the bit up into
the breaker before greasing will allow the
grease to fill the space between the top of the
bit and the breaker piston. When you next
use the breaker, the piston will pressurize this
grease and cause seal damage.
2.
Stop the engine and remove the key.
