NOTES

Chipper Limited Warranty

Crary Bear Cat Chippers are warranted for one year from date of sale for consumer and commercial or
rental operations.

Within the above stated period, Crary Co. will replace any part(s) found to be defective in material and/or

incurred in shipping part(s) are the responsibility of the purchaser.

This warranty is void in the case of accidents, failure to perform normal maintenance, or failure to follow
those instructions listed in the service manual. This warranty is also in lieu of all other expressed warranties
and voids any implied warranty as to the merchantability or fitness of the product for a particular purpose
and of any other obligation on the part of Crary Co. Some states do not allow limitations on how long the
implied warranty lasts, so the above limitation may not apply to you.

This warranty applies only to parts or components which are defective, and does not cover necessary

such as wheels, hoses, cables, chipper blades, chipper anvils, etc., are not included in the warranty.

Regular routine maintenance of the unit to keep it in proper operating condition is the
responsibility of the owner.

Engine warranty is not covered by Crary Co. Rather the warranty is covered by the engine manufacturer.

All warranty repair reimbursable under the Crary Co. warranty must be performed by an authorized Bear
Cat service dealer using Bear Cat approved replacement parts. Repair or attempted repair by anyone other
than an authorized Bear Cat service dealer is not reimbursable under the Crary Co. warranty. In addition,
these unauthorized repair attempts may result in additional malfunction, the correction of which is not
covered by warranty.

Crary Co. is not liable for indirect, incidental, or consequential damages in connection with the use of this
product including any cost or expense or providing substitute equipment or service during periods of
malfunction or non-use.

Some states do not allow the exclusion of incidental or consequential damages, so the above exclusion
may not apply to you. This warranty gives you specific legal rights. You may also have other rights which
vary from state to state.

Be sure to note the chipper serial number in any correspondence with Crary Co. or any authorized Bear
Cat dealer.

Assembly

Section

Your Chipper may arrive totally or partially assembled. If
your machine arrives partially assembled, perform the steps
in this section.

2.1 ADDING MOTOR OIL TO ENGINE
(ALL MODELS)

1. The machine’s engine ships filled with oil from factory
testing.

2. Refer to the engine owners manual to determine oil type
used.

3. Remove the oil fill plug.

4. Checking as necessary, add oil to the motor until the
dipstick shows the correct reading.

IMPORTANT

Check motor oil before
starting the chipper. Add
if necessary.

3. Fill the inlet line leading from the reservoir to the pump be­fore start-up. Loosen the fitting at the pump on this inlet line
until oil bleeds out.

4. Start the engine and run at the lowest possible RPM.

5. As you purge air from the unit, the oil level in the reservoir
will drop and bubbles may appear in the fluid. Refill the
reservoir as necessary.

6. Run the feed roller in both directions for several minutes
until any remaining air purges from the unit. Refill the reser­voir as necessary.

7. Shut down the engine, check for and correct any fluid leaks,
and check the reservoir level. Add fluid if necessary. The
hydraulic gear pump is now ready for operation.

2.2 ADDING HYDRAULIC FLUID

Hydraulic fluid drives the feed roller. The hydraulic pump is
attached to the motor (diesel models) or connected to the
motor with a belt (gasoline models).

The hydraulic pump requires premium hydraulic fluids
containing high quality rust, oxidation, and foam inhibitors.
These include premium turbine oils, API CD engine oils per
SAE J183, M2C33F or G automatic transmission fluids
meeting Allison C-3 or Caterpillar TO-2, and certain specialty
agricultural tractor fluids.

If system has no oil, follow this startup procedure:

1. Clean all system components (reservoir, fittings, etc.)
before starting the hydraulic pump.

2. After filtering the hydraulic fluid, fill the hydraulic reser­voir.
