Inspect Safety Valve
1. Pull ring on Safety Valve (see Figure 14) and ensure that
Safety Valve operates freely.
2. If valve is stuck or does not operate smoothly, it must be
replaced with same type of valve.Take unit to authorized
service facility for repair.
Inspect Quick Connect Fittings and
Tank Drain Valves
1. Turn engine ON/OFF switch to OFF position
(see Figure 9 earlier).
2. Move Fuel Shutoff Valve lever to OFF position
(see Figure 8 earlier).
3. Disconnect air hose(s), air tool(s), or accessory from
unit.Inspect Quick Connect fittings for damage and clean.
4. Pull ring on Safety Valve to reduce air pressure. Release
Safety Valve ring.
5. Open Drain Valves (turn fully counterclockwise,
see Figure 2, earlier) and discharge accumulated water.
Valves should operate smoothly and have full range of
operation.
6. After water has drained, close Drain Valves fully
clockwise.
NOTE: If Drain Valves are plugged, pull Safety Valve ring to
fully drain air from tanks. Remove, clean and reinstall Drain
Valves using pipe thread sealant.
Inspect Engine Oil Level
Oil Recommendations
NOTE: When adding oil to the engine crankcase, use only
high quality detergent oil rated with API service classification
SF, SG, SH, SJ or higher. DO NOT use special additives.
1. Choose a viscosity according to the table below:
* The use of multi-viscosity oils (5W-30, 10W-30, etc.) in
temperatures above 40°F (4°C) will result in higher than
normal oil consumption. Inspect oil level more often when
using a multi-viscosity oil.
** The use of SAE 30 oil in temperatures below 40°F (4°C)
will result in hard starting and possible engine bore damage
due to inadequate lubrication.
NOTE: Synthetic oil meeting ILSAC GF-2,API certification
mark and API service symbol with “SJ/CF ENERGY
CONSERVING” or higher, is an acceptable oil for use at all
temperatures. Use of synthetic oil does not alter required oil
change intervals.
Inspecting Engine Oil Level
Inspect oil level prior to each use or at least every 8 hours of
operation. Keep oil level maintained.
1. Make sure unit is on a level surface.
2. Remove Oil Fill Cap and wipe clean with cloth.
3. Verify oil is at the point of overflowing at oil fill opening.
Figure 14 - Safety Valve
• DO NOT direct air stream at self or others.
• Always wear ANSI Z87.1 approved safety glasses with side
shields.
Compressed air stream from hose or tank drain
can cause soft tissue damage to exposed skin and
can propel objects leading to severe injury
and / or property damage.
