Daily Maintenance
1. Remove hydraulic power from the tool and check all hydraulic
connections and hoses for damage. Replace damaged parts before
operating the tool.
2. Inspect the tool bit latch and associated parts. Replace when they have
become worn, cracked or distorted.
3. Inspect tool to ensure all stickers are legible. Contact STANLEY if
replacements are needed.
4. Check the flow and pressure of the hydraulic power source using a
calibrated flow meter. Proper flow and pressure maintain proper tool
speed. If tool speed increases or decreases, stop using the tool and
ensure proper flow and pressure.

The hydraulic power
source is not running
or not running
properly.
Ensure the power
source delivers proper
flow and pressure.
See “Specifications”
on page 9. Proper
flow and pressure
maintain proper tool
speed. Check regularly.
Couplers or hoses are
blocked.
Turn off and
disconnect the tool
from hydraulic power
source. Ensure no
blockage exists.
Low accumulator
charge.
Check and recharge
accumulator. See
“Check/Charge the
