OWNER SERVICE
The information in this section is written for operators
who possess basic mechanical skills. For your protec
-
tion, read and follow all safety information in this man
-
ual.
Before performing any service or maintenance,
lower digger to ground or block securely, turn off
tractor engine, remove key, and disconnect drive
-
line from tractor PTO.
NEVER GO UNDERNEATH EQUIPMENT. Never
place any part of the body underneath equipment
or between moveable parts even when the engine
has been turned off. Hydraulic system leak-down,
hydraulic system failures, mechanical failures, or
movement of control levers can cause equipment
to drop or rotate unexpectedly and cause severe
injury or death.
• Service work does not require going under
-
neath implement.
• Read Operator's Manual for service instruc
-
tions or have service performed by a qualified
dealer.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Keep hands, feet, hair, and clothing away from
equipment while engine is running. Stay clear of all
moving parts.
Keep hands and body away from pressurized
lines. Use paper or cardboard, not hands or other
body parts to check for leaks. Wear safety goggles.
Hydraulic fluid under pressure can easily penetrate
skin and will cause serious injury or death.
Make sure that all operating and service person
-
nel know that if hydraulic fluid penetrates skin, it
must be surgically removed as soon as possible by
a doctor familiar with this form of injury or gan
-
grene, serious injury, or death will result.
CONTACT A PHYSICIAN IMMEDIATELY IF FLUID
ENTERS SKIN OR EYES. DO NOT DELAY.
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
ROUTINE MAINTENANCE
1.
Check that all bolts, nuts, and screws are tight.
Checking the bolts and nuts on the cutting blades
is particularly important in rocky soil.
2.
Check daily the level of the gearbox oil and top-off
up to the correct level. Check for gearbox oil leaks.
It should be noted that no warranty claim can be
submitted on a gearbox that has run dry. It is
essential that the gearbox is kept correctly filled
with gearbox oil.
3.
Grease the PTO shaft daily.
4.
Check the wear on the cutting blades. Sharpen
them routinely with an angle grinder or replace
when worn down too far. Keep at least two sets of
cutting blades, bolts, and nuts as spares.
LUBRICATION INFORMATION
When lubricating telescoping PTO drives, keep
fingers out of shield access slots to prevent injury.
The accompanying chart gives the frequency of lubri
-
cation in operating hours, based on normal conditions.
Severe or unusual conditions may require more fre
-
quent lubrication.
Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
Use an SAE 90W gear lube in gearbox.
Use a lithium grease of No. 2 consistency with a MOLY
(molybdenum disulfide) additive for all locations. Be
sure to clean fittings thoroughly before attaching
grease gun. When applied according to the lubrication
chart, one good pump of most guns is sufficient. Do not
over grease.
