Do not mix oil with gasoline.

Break-In Procedures

Open outlet valve to prevent pressure from building up
in the tank. Set toggle lever of unloader valve in the
vertical position to relieve compressor head pressure.
See figure 4. Move the choke lever to "choke" position
and move on-off lever to the "on" position. See figure 5.
Pull choke all the way out. Move stop switch away from
spark plug.

Figure 5
A warm engine requires less choking than a cold engine.
Unit is top heavy. Make sure the compres-
sor is stable and will not tip before pulling
the starting cord.
1. Place your left hand on the air compressor handle,
and your right hand on the starter handle, and pull
cord out quickly to overcome engine compression
and prevent "kickback". If engine does not start,
push the choke about three-quarters of the way in or
choke level three quarters to the left and pull starter
handle again. When engine starts, push choke in or
choke lever to the left gradually.
Serious damage may result in the following
break-in instructions are not followed.
2. Pump Break-in: Open the outlet valve to prevent tank
pressure build-up. Run the air compressor for 30
minutes to seat the rings and lubricate all internal
surfaces. This operation must be completed only
once when first putting the unit in service.
3. After completing the above, and when ready to begin
using the compressor, move the unloader valve
toggle lever to a horizontal position. Close the outlet
valve to build tank pressure.
4. Engine Break-in: After the first 5 hours of normal
running, change the engine oil. Then after every 25
hours the engine oil should be changed.
