MODEL 20XP MAINTENANCE
14. Grease loader and grapple (if equipped):
Grease all loader and grapple pins and bushings with
1 to 2 shots of an EP-2 Lithium type grease. Wipe o
excess grease. Excessive grease will attract dirt.
NOTE: May accept grease easier after the loader
has been operated.
15. Check and oil feedwheel slide box:
Check that the feedwheel slide box is working
smoothly and oil with 10W/30 type motor oil. Clean
and oil the slide guides. After pinning, chaining, and
blocking the top yoke in the up position, clean and
oil each side of the bottom yoke. New machines,
especially, need oiling to ensure correct operation
during break-in.
16. Check / adjust the chipper drive belt tension:
Inspect belt condition and replace if needed. The
belts will need to be tightened several times in the
rst few days of operation. A loose belt will slip and
then glaze over. Once they slip you must replace
them. Check hydraulic pump drive belts also if
equipped. See pages 64 - 65 for procedures.
17. Check chain drive tension:
Check tension on all chain drive and tighten as
necessary. Chain tension is 1/4” (6 mm) per foot
(0.3m) of center distance between sprockets, NOT
to exceed a 1/2” (13 mm). Do not over tighten, which
may result in premature bearing and hydraulic motor
failure.
18. Check the hydraulic pumps and motor shafts:
Check the hydraulic pumps and hydraulic motor
shafts for t and tightness.
19. Check hydraulic oil level:
The hydraulic oil reservoir tank level should always
remain at 3/4 to 7/8 full. Remember to check DAILY
to avoid excessive heat build up.
20. Check hydraulic shut-o valves:
Check to ensure all shut-o valves are open.
21. Check for any uid leaks:
Inspect for any oil, fuel, hydraulic oil, or engine
coolant leaks. Check all hoses, ttings, lines, and
tanks. DO NOT use ngers or skin to check for
hydraulic leaks. Repair or replace any damaged or
leaking components.
22. Check hydraulic control valves:
Inspect all hydraulic control valves and ensure they
operate smoothly and shift correctly.
23. Check the fuel level:
Check the fuel level, running out and repriming is
time consuming. Do not over ll, and you must leave
fuel expansion space in the top of the tank.
8. Check chipper disc/drum to turn:
Very carefully, manually with a pry bar or wood
bar, turn the chipper disc/drum a full revolution.
This is to ensure the anvil and knives have proper
clearance. If the chipper disc/drum is jammed with
debris or frozen in place, DO NOT attempt to start
the engine and engage clutch until the chipper
disc/drum rotates freely.
9. Check the condition of the knives, anvil,
and attaching hardware:
Grind, le, or replace the knives to keep them
sharp. Check the anvil and attaching hardware for
the knives and anvil. Replace if necessary.
10. Properly torque the knife mounting hardware:
All knife mounting hardware must be factory
approved. Knife mounting hardware must
be replaced after maximum of 4-5 knife
rotations/changes to ensure safe clamping ability.
Torque set, AT ALL TIMES to: See TORQUE
CHART on page 44.
11. Hood lock pin and padlock:
After closing chipper hood, reinsert the hood pin and
padlock, make sure pin is tight and secure. If worn
replace immediately. Don’t use a worn or makeshift
hood pin. Make sure the spring lock for the hood
pin is in the correct position on disc chippers. Make
sure the chipper hood engine disable plug is installed
correctly and that it is also operating properly.
12. Grease chipper bearings daily:
Use an EP-2 Lithium type grease only for all
bearings. Purge chipper bearings with grease. You
can not over grease these bearings. This type of
bearing is designed with a relief system that will
not allow over greasing. In other words, you can
not hurt the bearing seals by pumping in too much
grease. Most of the failures related to bearings are
diagnosed as “Contamination”. Contamination is
caused by improper lubrication. Wipe o excess
grease. Excessive grease will attract dirt.
13. Grease all feedwheel and conveyor bearings
daily:
Use an EP-2 Lithium type grease only for all
bearings. Grease feedwheel and conveyor bearings
with one shot of grease. This type of bearing is
designed with a relief system that will not allow
over greasing. In other words, you can not hurt the
bearing seals by pumping in too much grease. Most
of the failures related to bearings are diagnosed
as “Contamination”. Contamination is caused by
improper lubrication. Wipe off excess grease.
Excessive grease will attract dirt.
