Maintenance
Do not change accessories, inspect, adjust or
clean tool when it is connected to a power source.
Accidental startup could result in serious injury or

Wear eye protection when

Failure to wear eye protection could
result in serious eye injury from
flying debris or hydraulic oil.
Use this maintenance schedule to maximize the tool’s
service life.
Note: Keep decals clean and legible. Replace decals
when necessary.
When disposing of any components (hydraulic hoses,
hydraulic fluid, worn parts, etc.), do so in accordance
with federal, state, and local laws or ordinances.
Daily
1. Wipe all tool surfaces clean.
2. Inspect the hydraulic hoses and fittings for signs
of leaks, cracks, wear, or damage. Replace if
necessary.
3. Install dust caps over the hydraulic ports when the
tool is disconnected.
4. Apply a light oil to all moving parts.
Monthly
Perform a thorough inspection of the hydraulic hoses
and fittings as described in publication 99930323,
SAE J1273 (Hose and Hose Assemblies).
Annually
If required by your organization, have the tool
inspected by an authorized Greenlee Utility service
center.
Storage
If the tool requires long-term storage, protect the
striking piston against corrosion. Press the striking
piston to its upper position (through the anvil bushing).
As the quick-release couplings are blocked when
disassembled, the striking piston must be pressed
upward with the hoses mounted but the power source
turned off.
