This document is an instruction manual for a range of Rok direct drive oil-lubricated piston air compressors. The manual covers three specific models: 150-02-50222 (24 Litre, 1.5HP), 150-02-50243 (40 Litre, 2.0HP), and 150-02-50474 (40 Litre, 2.5HP). It provides essential information regarding the compressor's function, technical specifications, usage, safety precautions, maintenance, and warranty details.

Function Description

The Rok air compressors are designed to compress normal air for various light-duty applications. They are piston-type compressors, meaning they use a piston mechanism to draw in and compress air, which is then stored in a tank. The compressed air can be used to power a variety of air tools. The compressors are oil-lubricated, indicating that the internal moving parts of the pump are lubricated with oil to reduce friction and wear, ensuring smoother operation and longevity.

The operation of the compressor is controlled by a pressure switch. When the pressure in the tank reaches a preset maximum, the pressure switch activates and turns off the motor. As air is used and the tank pressure decreases to a preset minimum, the pressure switch turns the motor on again to re-pressurize the tank. This automatic cycling ensures a consistent supply of compressed air. The compressor features both a direct outlet and a regulated outlet. The pressure of the regulated outlet can be adjusted by turning a control knob, allowing users to match the air pressure to the specific requirements of their air tools. A safety valve is included to prevent over-pressurization of the air tank, automatically releasing air if the pressure exceeds a safe limit. A drain cock at the bottom of the tank allows for the removal of condensation, which is crucial for maintaining the compressor and preventing corrosion.

Important Technical Specifications

The manual provides a detailed specification table for the three models:

• Model Numbers: 150-02-50222, 150-02-50243, 150-02-50474
• Tank Capacity: 24 Litres (for 150-02-50222), 40 Litres (for 150-02-50243 and 150-02-50474)
• Voltage: 230V/50HZ for all models, indicating they are designed for standard Australian/New Zealand electrical mains.
• Motor Horsepower (HP): 1.5 HP (150-02-50222), 2.0 HP (150-02-50243), 2.5 HP (150-02-50474)
• Ampere (Amp): 5.0A (150-02-50222), 7.0A (150-02-50243), 9.0A (150-02-50474)
• Speed: 2850 RPM for all models, indicating the rotational speed of the motor.
• Drive Pump: Φ42X1 (150-02-50222), Φ48X1 (150-02-50243 and 150-02-50474). This likely refers to the cylinder bore and number of cylinders.
• L/min (Air Delivery): 136 L/min (150-02-50222), 206 L/min (150-02-50243), 250 L/min (150-02-50474). This indicates the volume of air the compressor can deliver per minute.
• Outlet: 1 x 1/4" for all models, specifying the size of the air outlet connection.
• Wheels: 4.5" (150-02-50222), 6" (150-02-50243 and 150-02-50474), indicating the diameter of the wheels for portability.
• Max Pressure: 800 kPa / 8.0 Bar for all models, which is the maximum operating pressure.

The compressors are fitted with a sealed electrical connection plug compatible with Australian/New Zealand mains power supply.

Usage Features

Assembly: The compressor requires minor assembly before use. This includes fitting the wheels and axle set, inserting a rubber stopper into the tank's spigot, attaching the air filter to the cylinder head, and replacing a plastic dust plug with an oil breather in the oil breather hole. Failure to fully assemble the compressor voids the warranty and may result in personal injury.

Oil Warning and Lubrication: The unit is shipped with oil in the compressor pump. Before initial use, the dust cover must be removed and replaced with the oil breather. The oil level should be checked to ensure it reaches the top of the red mark on the sight glass. The small hole in the top of the breather pipe must be clear before insertion into the oil filler hole.

Initial Startup: Before starting, ensure the unit is stable on a level, well-ventilated, dry surface. The drain valve and all air outlets must be closed. Connect the power lead to the mains. The compressor is started by pulling on the red knob (pressure switch). The red knob should be used to turn the unit on and off, not the mains switch, as using the mains switch for this purpose can damage the motor.

Operation: The compressor operates intermittently with a recommended 50% duty cycle for domestic use (30 seconds ON, 30 seconds OFF). During the "ON" cycle (motor pumping), the attached air tool should not be used. Air tools should only be used when the compressor motor is not pumping, and usage should cease as soon as the motor starts pumping again. The maximum and minimum pressures are factory set and should not be altered. The regulated outlet pressure can be adjusted by turning the control knob clockwise to increase pressure and anti-clockwise to decrease it.

Suggested Applications: These compressors are suitable for light-duty air tools such as ball inflators, tyre inflators, touch-up spray guns, combo nailers, T-nailers, toy inflators, mini air brushes, staplers, and C-bradders. They are explicitly NOT recommended for use with heavy-duty spray guns or nail guns.

Safety Features:

• Work Area: Keep the work area tidy, well-lit, and free from obstructions. Maintain at least 5 meters distance between the compressor and the work area, especially when spraying.
• Stability: Ensure the compressor is level and stable to prevent lack of lubrication and pump seizure.
• Electrical Safety: Avoid body contact with earthed surfaces. The compressor must be plugged directly into a 240V AC wall socket; extension cords are not recommended as they can cause voltage loss and motor damage, voiding the warranty.
• Duty Cycle: Adhere to the 50% duty cycle (30 seconds ON, 30 seconds OFF) to prevent overloading and damage.
• Tool Selection: Use the right tool for the job; do not force a small compressor to do heavy-duty work.
• Power Cord: Do not abuse the power cord; keep it away from heat, oil, solvents, and sharp edges.
• Hot Components: Be aware that many components (metal pipes, pump, motor) become hot during use and should not be touched.
• Personal Safety: Wear safety goggles, ear protection, and a dust/filter mask when appropriate. Wear suitable non-slip footwear. Avoid loose clothing, jewelry, and tie back long hair.
• Children and Pets: Keep children and pets out of the work area and store the compressor securely out of their reach.
• Fire Precautions: Observe general fire precautions. Do not use the compressor in areas with a risk of explosion or fire from combustible materials.
• Damaged Parts: Do not use a damaged compressor. Any damaged parts or switches must be repaired or replaced by an authorized service facility.
• Modifications: Do not attempt to modify the air compressor, guards, or accessories, as this will void the warranty and could cause injury.

Maintenance Features

Daily Maintenance:

1. Check the oil level before each use.
2. Drain condensation from the air receiver (tank).
3. Check for air leaks.

Weekly Maintenance:

1. Remove and clean or replace the air filter element as required.

Monthly Maintenance:

1. Inspect the non-return valve (clean or replace as required). Ensure the air tank is empty before this operation.
2. Manually test the safety valve by pulling the ring.

Three-Monthly Maintenance:

1. Change the oil.
2. Tighten cylinder head bolts.
3. Clean and check the valve assembly; replace gaskets/valves if worn or damaged.

Oil Recommendations: Use SAE30 compressor oil for temperatures over 10°C and SAE10 for temperatures below 10°C. The oil must be changed after the first 10 hours of operation, and then every 20 hours thereafter.

General Maintenance:

• Keep handles clean, dry, and free from oil and grease.
• Ensure ventilation slots are kept clean and free from dust to prevent overheating.
• Disconnect the compressor from the mains supply before any servicing, lubricating, adjustments, or accessory changes.
• Always remove adjusting keys or wrenches before operating.
• Clean the compressor with a damp soft cloth after it has cooled (about one hour after use). NEVER use liquids or solvents.

The manual emphasizes the importance of following all instructions to ensure personal safety, maintain the device's longevity, and keep the warranty valid. It also provides contact information for customer service and warranty claims.
