Pre-Startup
Operation of the Grizzly must be restricted to operators who have read and completely understand all Safety
Rules, Precautions and Operating Functions of both Tractor (carrier) and the Alamo Grizzly.
Do not operate the carrier or the Grizzly when tired, ill or under the influence of drugs, alcohol or medication.

rocks, etc., from under the shroud. To minimize this danger:
Walk around the Grizzly and check it thoroughly for damage, loose bolts, missing cotter pins and wire or
rope etc., possibly wrapped around the shaft.
Peform the operations outlined on the following Daily Check List.
DAILY CHECK LIST
Check:
Grizzly to carrier mounting pins for security & wear Check all cutter blades/bits for condition & retention
Grizzly frame and shroud for damage Main shaft and cutters for wire, rope or other
material wrapped around
Motor and motor baseplate bolts for security Hydraulic lines & connections for chafing, leaks or
looseness
Check all mounting adapter bolts Hydraulic oil level in tank, top up as necessary
Lubricate:
Remove:
Upper and lower bearing. Use Shell EP2 or equal.

usually sufficient. Over-greasing will cause high
bearing housing temperature.

good quality grease
