Maintenance Schedule

The service life of the tool will be maximized by proper
care and maintenance. The maintenance schedule that
follows is recommended.
• Do not change accessories, inspect, adjust or
clean tool when it is connected to a power
source. Accidental start-up can result in serious
injury.
• Inspect the cutter blade every operating day.
Remove and destroy cutter blade if cracks,
chips, or gouges are evident. A damaged blade
can break and strike nearby personnel.
Inspect hydraulic hoses and couplings every
operating day. Repair or replace if leakage,
cracking, wear, or damage is evident. Damaged
hoses or couplings can fail resulting in injury or
property damage.

Daily:
1. Wipe all tool surfaces clean.
2. Inspect the cutter unit. Check for wear at the
pivoting and sliding surfaces. Repair the blade with
a very fine file and a pocket whetstone. Remove
and destroy any cutter blade with severe cracks,
chips or gouges.
3. Lubricate the pivoting and sliding surfaces several
times every operating day with 20W or 30W oil.
Apply a heavy coating to these surfaces before
storing.
4. Several times a day the blade and hook must be
dressed with a pocket whetstone. This keeps the
cutting edge from rolling and chipping.
5. Make sure the extension tube connector nut and
the cutter mounting bracket bolts are tightened
securely.
6. Inspect hydraulic system hoses and fittings for signs
of leaks, cracks, wear, or damage.
7. To prevent contamination, always install dust caps
over couplers when tool is disconnected.
Monthly:
Perform a detailed inspection of the hydraulic system
hoses and fittings as stated in Appendix A - S.A.E.
Standard J1273, May 1986. Replace the hose and/or
fittings if necessary.
Lubrication (see Figure 3)
Lubricate the indicated pivoting and sliding surfaces
several times every operating day with 20W or 30W oil.
Apply a heavy coating to these surfaces before storing.
