ed in the air or with minimal down pressure, turn on

the breaker to gradually warm up its internal com-

ponents.

3. When the hydraulic system and breaker are warm,

proceed with operation. See the OPERATION sec-

tion of this manual.

LONG TERM STORAGE

Use the following procedure if storage of the break- er is expected to be more than 6 months.

IMPORTANT: The piston protrudes out the bottom of the cylinder when not in use, although it is inside the lower body it will still be exposed to the elements and will rust damaging internal components when it is put back into service.

Remove the tool bit and discharge the nitrogen gas from the upper accumulator. Use the tool bit to push the pis- ton inside the cylinder where it will be protected from the elements. Grease the lower end of the exposed piston thoroughly. Also thoroughly coat the tool bit, tool stop, retaining pins, and lower bushing with grease.

If hoses are attached to the breaker, install plugs on the hose ends. If hoses are removed from the breaker, install plugs on the hose ends and install plugs in the breaker “IN” and “OUT” ports.

Store breaker in a dry area under cover if possible. It is best to store the breaker in an area that has a consistent temperature to help avoid water condensation causing rust. Store the breaker in a vertical position. Do not store the breaker horizontally for extended periods.

If the breaker has been laid horizontally for more than 6 months, check and/or replace all seals. Check for corro- sion of bolts before operation.
