IMPORTANT SAFETY INSTRUCTIONS FOR AIR COMPRESSORS

• RISK OF EXPLOSION OR FIRE WHAT CAN HAPPEN
  It is normal for electrical contacts within the motor and pressure switch to spark. If electrical sparks from the compressor come in contact with flammable vapors, they may ignite, causing fire or explosion. Restricting any of the compressor air filters will cause serious overheating and could cause fire.

• RISK OF BURSTING WHAT CAN HAPPEN

1. Failure to properly drain condensed water from the tanks, causing rust and thinning of the steel tanks.
2. Modifications or attempted repairs to the tanks.
3. Unauthorized modifications to the unloader valve, safety valve or any other components which control tank pressure.
4. Excessive vibration can weaken the air tanks and cause rupture or explosion.  

Attachments & Accessories; Exceeding the operating pressure of air tools can cause them to explode.

• RISK OF BURNS WHAT CAN HAPPEN
  Touching exposed metal such as the compressor head or outlet tubes, can result in serious burns.

• RISK OF PROPERTY DAMAGE WHEN TRANSPORTING COMPRESSOR WHAT CAN HAPPEN
  Oil can leak or spill and could result in fire or breathing hazard, serious injury or death can result. Oil leaks will damage carpet, paint or other surfaces in vehicles or trailers.

• HOW TO PREVENT IT
  Always operate the compressor in a well ventilated area free of combustible materials, gasoline or solvent vapors. If spraying flammable materials, spray material at least 20 feet away from the compressor. An additional length of hose may be required. Store flammable materials in a secure location away from the compressor. Never place objects against or on top of the compressor. Operate compressor on a stable level surface in a clean, dry and well ventilated area.

• HOW TO PREVENT IT
  Drain tanks daily or after every use. If the tanks develop a leak, replace tanks or get a new air compressor. Never drill into, weld or make any modifications to the tanks or its attachments. The tanks are designed to withstand specific operating pressures. Never make adjustments or parts substitutions to alter the factory set operating pressures. Regulate the output air pressure using the regulator.

• HOW TO PREVENT IT
  Never touch any exposed metal parts on compressor during or immediately after operation. The compressor will remain hot several minutes after use. Do not reach around the pump and/or engine or attempt maintenance until these components have cooled down completely.

• HOW TO PREVENT IT
  Always place compressor on a protective mat when transporting to protect against damage to vehicle from leaks. Remove compressor from vehicle immediately upon arrival.

This air compressor and other components used make up a high pressure system, the following safety rules and guidelines should be followed when using, cleaning or servicing.

1. Read and understand instruction manual before attempting to install and use compressor. Be thoroughly familiar with the operational controls and proper use.
2. Applications requiring air free of oil or water should have the appropriate filters/water traps installed in the pressure system.
3. Wear safety glasses.
4. Do not operate if any part is damaged during shipping, handling or use, have the part replaced or repaired before attempting to use.
5. Never operate the compressor with the belt guard removed, this compressor can start automatically without warning. Personal injury or property damage could occur from contact with moving parts.
6. Never attempt to modify or adjust the ASME safety valve. The safety valve must be kept clean and free from paint or any other type of accumulation.
7. Never attempt to repair or modify air tanks. Welding, drilling or any other modification will weaken the air tanks resulting in damage from rupture or explosion.
8. Drain water from tanks on a regular basis. Tanks rust from moisture build-up which weakens the air tanks.

PRE-START CHECK

WARNING! To prevent permanent damage to your air compressor gasoline engine, you MUST check oil level, fuel level and air cleaner filter before starting.

PRE-START CHECK OIL LEVEL

• WARNING! This engine has been shipped from the factory without oil or very little oil in the crankcase. Operating your engine without the correct amount of oil can damage it.
• Oil crankcase capacity: 0.6 litres. Always check the oil level before starting the engine. To check oil level;

1. Turn the oil gauge dipstick (A) Fig.1 counterclockwise, remove it and clean it with a clean cloth.
2. Fully reinsert the oil gauge dipstick and pull it out to check the oil level.
3. If the oil level is halfway up the dipstick or below, refill with SAE 10W30 oil through the dipstick hole until the oil level reaches 3/4 up the dipstick or until it reaches the bottom lip of the dipstick hole as shown in illustration. ****
4. Reposition the oil gauge dipstick and tighten it by turning clockwise.

• FUEL LEVEL
  WARNING! Make sure there is enough fuel in the fuel tank before operating.

1. If it is necessary to add fuel, first make sure the engine switch is OFF, then open the fuel cap (A) Fig.2 by turning it counterclockwise.
2.  Make sure the fuel filter cup (B) is positioned inside the tank opening before refueling.
3. Do not fill the fuel tank past the fuel cup (B). When refueling, keep in mind all safety precautions and make sure to add enough fuel based on usage. Use clean unleaded gasoline with a minimum of 87 octane. Do not mix oil with gasoline. Fuel tank capacity: 3.6 litres.

• AIR CLEANER FILTERS
  The air cleaner filters should be checked before every start-up and after prolonged storage, the following steps should be done when checking air cleaner filters;

1. Remove the nut (B) Fig.3, lift to remove the air cleaner cover (A) as shown.

IMPORTANT AIR COMPRESSOR BREAK-IN PROCEDURES

NOTE:

SERIOUS DAMAGE TO THE AIR COMPRESSOR MAY RESULT IF THE FOLLOWING BREAK-IN INSTRUCTIONS ARE NOT CLOSELY FOLLOWED. THESE PROCEDURES ARE REQUIRED BEFORE THE AIR COMPRESSOR CAN BE PUT INTO SERVICE, AFTER REPLACING THE CHECK VALVE, AND WHEN A PISTON OR A CYLINDER SLEEVE ARE REPLACED.

1. Make sure the oil level in the crankcase reaches the centre dot of the oil sight glass (A) Fig.6. If needed, refer to maintenance section in this manual for instructions on filling the crankcase with oil. Pull then turn regulator knob (A) Fig.7 counterclockwise to open air flow.
2. Move load master valve lever (B) Fig.7 to a horizontal position (unloaded position) as shown to allow the compressor pump to run without compressing air.
3. Make sure there is sufficient amount of fuel in the gas tank and oil in the engine crankcase.
4. Run the engine/compressor for 15 minutes. Make sure there is no tank pressure build-up (tank pressure gauge at zero).
5. After 15 minutes, move load master valve lever (B) Fig.7 down (loaded position) and turn the regulator knob clockwise. The compressor will begin to pump air in the air tanks.
6. When maximum tank pressure is reached, the compressor automatically unloads, bringing the engine to idle speed. The engine will remain at idle speed until tank pressure drops below the cut-in pressure setting. The engine then accelerates and the compressor pumps additional air into the air tanks. The compressor is now ready for use.

COMPRESSOR CONTROLS

ADDITIONAL REGULATORS AND CONTROLS
Since the air tank pressure is usually greater than that which is needed, an air pressure regulator is employed to control the air pressure ahead of any individual driven device. Separate air transformers which combine the function of air regulation, moisture and dirt removal should be used where applicable.

OPERATION CONTROLS

• THROTTLE UNLOADER (A) FIG.8. The throttle unloader automatically slows down the engine to idle speed when the air tank pressure reaches the factory set “Cut-Out” pressure (maximum pressure). When the tank pressure drops below the factory set “Cut-In” pressure, the engine will automatically accelerate and the compressor will pump additional air into the air tanks.

• TANK PRESSURE GAUGE (B) FIG.8. The tank pressure gauge indicates the reserve air pressure in the air tanks.

• OUTLET PRESSURE GAUGE (C) FIG.8. The outlet pressure gauge indicates the air pressure available at the outlet side of the regulator. The pressure is controlled by the regulator and is always less than or equal to the tank pressure.

• REGULATOR (D) FIG.8. The air pressure coming from the air tanks is controlled by the regulator. To unlock the regulator, pull it outwards then turn the regulator knob clockwise to increase pressure or counterclockwise to decrease pressure. To avoid minor readjustment after making a change in the pressure setting, always approach the desired pressure from a lower pressure. When reducing from a higher to a lower setting, first reduce the pressure less than that desired, then bring it up to the desired pressure. Depending on the air requirements of each particular accessory, the outlet regulated air pressure may have to be adjusted while operating the accessory.

• ASME SAFETY VALVE (E) FIG.8. The safety valve protects against over pressurization by “popping out” at its factory set pressure of 150 PSI.
  WARNING!: If the safety valve does not work properly, over pressurization may occur, causing air tank rupture or an explosion. Daily pull the ring on the safety valve to make sure that the safety valve operates freely. If the valve is stuck or does not operate smoothly, it must be replaced with an identical 150 PSI ASME approved safety valve.

• CHECK VALVE (F) FIG.8. When the air compressor is operating, the check valve opens, allowing compressed air to enter the air tanks. When the air compressor reaches its “Cut-Out” pressure, the check valve closes, allowing air pressure to remain inside the air tanks.

• DRAIN VALVES (A & B) FIG.9. The drain valves are located underneath each end of the air tanks and are used to drain condensation at the end of each use. Turn drain valve counterclockwise to open (no tank pressure build-up) or clockwise to close it (pressure build-up). 1/4” QUICK CONNECT COUPLERS (A & B) FIG.10. These 1/4” universal “one touch” quick connect couplers allow user to connect up to 2 air hoses to operate 2 air tools.

OPERATIONAL GUIDELINES & MAINTENANCE

OPERATIONAL GUIDELINES

Factory Pressure Setting & Adjustment This compressor comes with a factory operating pressure setting of 95-125 PSI (cut-in and cut-out), the cut-out pressure setting may be increased up to 150 PSI by making an adjustment to the load master valve assembly Fig.11. Caution! We strongly recommend keeping the cut-out pressure setting between 125-135 PSI. Exceeding this pressure will put additional strain on the engine and pump and may cause the safety valve to occasionally “pop”. To increase the cut-out pressure setting, using a wrench, loosen the load master valve (A) Fig.11 by turning it counterclockwise. Then turn the load master valve fitting (B) clockwise. Make small adjustments at first and test the new setting until the desired cut-out pressure setting is obtained. Retighten the load master valve.

Moisture in compressed air

When humidity is high or when the compressor is in continuous use for an extended period of time, this moisture will collect in the air tanks. When using a spray gun or sandblast gun, this water will be carried from the tank through the hose and out of the gun as droplets mixed with the spray material. This will cause water spots in a paint job, especially when spraying other than water based paint. If sandblasting, it will cause the material to cake and clog the gun, rendering it ineffective. An optional air control unit with dirt and moisture removal should be used to prevent these undesirable results.

MAINTENANCE

Before doing any maintenance or adjustments to your air compressor, the following safety precautions should be taken:

• Turn the engine off and drain air tanks of pressure.

After Use:

1. Turn engine off.

2. Pull ring on safety valve (E) Fig.8, allowing air to bleed from the tanks until tank pressure is approximately 20 PSI. Release safety valve ring.

3. Drain moisture/water from air tanks. Open drain valves (A & B) Fig.9, turn them counterclockwise to open.
   WARNING!: Water will condense in the air tanks. If not drained water will corrode and weaken the air tanks causing a risk of air tank rupture. NOTE: If a drain valve is plugged, pull ring on safety valve (E) Fig.8, and hold until all air pressure has been released. The valve can then be removed, cleaned, and reinstalled.

4. After the water has been completely drained, turn drain valves clockwise to close.

Daily or before each use

1. Check pump oil level. Oil level must be in the centre of the red dot of oil sight glass.
2. Drain condensation from tank.
3. Check for any unusual noise or vibration.
4. Be sure all nuts and bolts are tight.

Monthly

1. Inspect air system for leaks by applying soapy water to all joints. Tighten those joints if leakage is observed.

Initial pump oil change must be done after the first 100 hours

1. Once initial pump oil change is done after 100 hours of operation, change pump oil every 300 hours or 6 months, which ever comes first. See changing oil instructions.
2. Replace oil more often if used near paint spraying operations or in dusty environments.

• CHANGING OIL
  To change oil, oil must be drained from the crankcase by removing oil drain bolt (A) Fig.12. Drain oil and replace oil drain bolt. To fill the crankcase with oil, first unscrew and remove oil fill cap (B), pour air compressor oil (approx. 900ml of SAE 30 weight non-detergent oil) into oil opening until the oil level reaches the red dot at the centre of the oil sight glass (C). Reinstall the fill cap (B).

• KEEP COMPRESSOR CLEAN
  Periodically blow out all air passages with dry compressed air. Clean all parts with a soft damp cloth. CAUTION: Wear safety glasses while using compressed air.

MAINTENANCE

REPLACING/TENSIONING DRIVE BELT
If the drive belt needs tensioning, the belt should be adjusted so when pressure is applied in the centre, there is approximately 1/2” slack. See Fig.13.

MAINTAINING YOUR ENGINE
Engine Oil Replacement Oil crankcase capacity: 0.6 litres.
Engine oil should be replaced after the first 20 hours of operation or after the first month of use, it should be replaced every 100 hours or 6 months after. To replace engine oil:

1. Loosen the oil gauge dipstick (A) Fig.14.
2. Place an oil pan underneath drain hex. bolt (B), remove hex. bolt (B) and drain oil.
3. Once all the oil has completely drained, retighten the hex. bolt (B).

Recommended Engine Oil
It is recommended to use SAE 10W30 4-stroke gasoline engine oil. For cold weather (below -15ºC) use SAE 5W30.

• Fill with clean engine oil through the oil gauge dipstick hole, fill then check oil level until the oil level reaches 3/4 up the dipstick or until it reaches the bottom lip of the dipstick hole as shown in the illustration above.

Inspecting, Replacing or Cleaning Spark Plug (F7TC or equivalent)

The spark plug should be checked every 100 hours of operation or every 6 months. To replace or clean spark plug: 1) Dismantle the spark plug cap (A) Fig.15 by pulling it off the spark plug (B). Using the supplied spark plug wrench, undo the spark plug by turning it counterclockwise. 2) Check to see if there is carbon sediment build-up, if so just remove it. If the carbon sediment is excessive, replace the spark plug. 3) Measure the electrodes clearance. See Fig.16. The spark plug electrode clearance should be between 0.7-0.8mm. If the clearance exceeds 0.8mm, replace the spark plug with an LD F7TC or equivalent (NGK BP6ES, Champion N9Y). 4) Reinstall spark plug in the reverse order
