Model H3370/H3371Air Compressors -7-
PREPARING FOR USE
Before using your Grizzly Air
Compressor, follow these steps:
1. Remove all packing materials and any
protective plastic bags, zip tie labels
or tags from the compressor.
2. Be sure the air filter is attached to the
cylinder head as shown in Figure 2.
Figure 3.
Proper oil level.
4. Make sure the drain valve on the air
tank is closed.
3. ADD OIL TO THE CRANKCASE. Oil
has been supplied with your air com-
pressor. Remove the oil breather on
top of the crankcase and add oil into
the hole. The oil level should be in the
center of the sight gauge shown in
Figure 3.
NOTICE
The machine should never be run
without a full oil reservoir. The oil
provides lubrication to the cylinder
rings which deliver the compressed
air. Severe damage to the internal
moving parts can occur if there is
not adequate oil flow. Check the oil
level frequently, and change the oil
every 3 months.

Duty Cycle
5. Know and understand the duty cycle
of the compressor before operating.
Overheating, short circuit and fire
damage will result form operating
beyond the recommended duty
cycle. Severe injury and property
damage could occur.
The Model H3370/H3371 Air Compressor
should NOT be operated on more than a
50% duty cycle. (This means an air com-
pressor that pumps air for over 30 minutes
in one hour is considered misuse. This
could mean that the air compressor is
undersized for the required air demand.
Note—The maximum compressor pump
time per hour is 30 minutes.
