Stump Grinder Operation
DANGER
!
To avoid serious injury or death:
Clear area of all bystanders before turning on hydraulics to
the grinder. Keep all bystanders away while grinder is
operating. Turning on hydraulics powers the cutting wheel
and hydraulic cylinders. Anyone close by can become
pinched, crushed, and/or entangled in the grinder while it is
operating causing serious injury or death.
WARNING
!
To avoid serious injury or death:
•
Clear all debris from cutting area before operating unit.
Keep all bystanders at a safe distance away from product
being discharged. Wood chips and debris can discharge at
high speeds causing serious injury or death.
•
Never make contact with underground utilities such as
electrical power lines, gas lines, phone lines, etc. They can
cause serious injury or death from electrocution, explosion,
or fire. If in doubt, call 811 (USA) before digging so that
they can mark the location of underground services in the
area. For contact information, see Dig Safe in the
“Important Safety Information” starting on page 1.
1. Be sure to read and understand all safety alerts
under
Operating Safety
on page 15:.
2. Check for overhead and below ground obstructions
before grinding stump.
3. If attachment is to be operated in reverse, make sure
visibility to the rear is appropriate for the attachment.
Backup camera or mirror is recommended. Maintain
cleanliness of lens or mirror.
Refer to Figure 3-2 on page 18:
4. Fully retract tilt cylinder (#1) and extend or retract
articulation cylinder (#2) so that the cutting wheel is
centered on the stump.
5. Move skid steer forward until cutting wheel is located
on far side of stump as shown.
6. Lower skid steer hitch down until skid shoes are
firmly planted on the ground. See “Skid Shoe
Adjustment”
on page 14 for detailed adjustment
instructions. If available, set skid steer park brake.
IMPORTANT:
Do not backup or move forward while
Stump Grinder is removing wood chips. Doing so
can cause vibration and may damage hydraulic
motor and other components.
IMPORTANT:
Make sure skid shoes are firmly
planted on the ground and if available, park brake is
set before operating Stump Grinder. This will help
prevent skid steer movement, minimize vibration,
and help protect against structural damage.
NOTE:
Rate and depth of cut is determined by
sharpness of rotary teeth, density of wood, and
condition of wood.
Start of First Cut
Figure 3-1
7. Rotate top of skid steer hitch plate forward or
rearward until cutting teeth are just above the stump.
8. Using articulation cylinder (#2), move cutting wheel
to the right as shown in Figure 3-1 and engage
hydraulics to rotation start cutting wheel rotation
.
9. Slightly extend tilt cylinder (#1) to lower carbide teeth
enough to make a cut into the stump as shown in
Figure 3-3 on page 18.
Refer to Figure 3-1:
10. Slowly retract articulation cylinder (#2) to make a
cross cut across top of stump.
11. Once cutting wheel has made a full swing across top
of stump, extend tilt cylinder (#1) to make another cut
and start back across the stump.
12. Continue swinging cutting wheel back and forth
across top of stump and extending tilt cylinder at start
of each new pass until depth of cut is around 4" deep
in the stump.
13. Fully retract tilt cylinder (#1), raise loader arms up
several inches, and back skid steer up to a new
location to continue removing chips from the stump.
14. Repeat steps 9 to 13 until top of stump has been
completely removed to the 4" depth as shown in
Figure 3-4 on page 18.
15. Raise loader arms up several inches and drive
forward to reposition cutting teeth just above far side
of remaining stump and to the right side.
16. Repeat steps 9-15 until the stump has been removed
approximately 8" below ground as shown in
Figure 3-5 on page 18.
