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 cylinder
head or oil plug.
2. Be sure the air filter is attached to the
cylinder head.
Figure 2.
Proper oil level.
4. Make sure the drain valve under the
air tank is closed.
3. ADD OIL TO THE CRANKCASE. Oil
has NOT been supplied with your air
compressor. The oil level should be in
the center of the sight gauge shown in
Figure 2. Use compressor oil or non-
detergent 30 WT oil.
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
on a regular schedule.
Duty Cycle
The Model H4519 3 HP 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.
The maximum compressor pump time per
hour is 30 minutes.
Always be aware of the duty cycle for
your air compressor. Failure to oper-
ate the air compressor properly
could result in overheating and
motor seizure. There could also be
risk of fire hazard due to overheat-
ing. Be sure to use a compressor
capable of handling the air demand.
