Air Supply

FAILURE TO FOLLOW THESE INSTRUCTIONS WILL LEAD TO PREMATURE MALFUNCTION OF THE EQUIPMENT WHICH IS NOT COVERED BY THE GUARANTEE.

HYDRAULIC FLUID SPECIFICATION:
Hydraulic fluid viscosity refers to it’s properties to flow and how it reacts with heat. A low viscosity is thinner than a high viscosity.
Hydraulic fluid becomes thinner as it heats so choosing the right viscosity is essential. If the viscosity is too low it may provide insufficient lubrication when heated. Equally if it is too high the fluid may provide excessive resistance to move through the lines when cold.
The ISO (International Standards Organisation) viscosity grading system measures the kinematic viscosity in centistokes (cSt) at 40° which is today accepted standard. The SAE (Society of Automotive Engineers) viscosity grade value is based on a scale.
This equipment is suited to an ISO grade 22-32 (SAE grade 5W-15W) hydraulic fluid or monograde oil.

The fluid must be constantly supplied to the equipment during use to ensure complete lubrication and optimum performance is achieved. It also acts as a rust inhibitor when the equipment is not in use. Most of the major brand petroleum companies produce a suitable lubricant to the above specifications.
This air tool operates at a maximum pressure of 90psi and must be controlled via a combination pressure regulator, in-line lubricator and moisture filter such as the Draper range (see your local Draper stockist) which with proper maintenance will ensure a constant supply of dry air and lubricating oil at all times (see illustration below). Always check machine operating pressure before use.
WATER IN THE COMPRESSOR TANK WILL CAUSE SERIOUS CORROSION TO YOUR AIR TOOLS AND SHOULD BE DRAINED DAILY TO AVOID EXCESSIVE WATER IN YOUR AIR SUPPLY. DIRTY WET AIR RAPIDLY SHORTENS THE LIFE OF YOUR AIR TOOL.
If you are using an air tool on a hose over 25ft. long it is advisable to increase the bore of the hose to the next larger size available i.e.. 1/4″ increases 3/8″. This will ensure adequate pressure and volume of air to power the machine.

RECOMMENDED AIR SUPPLY SET UP

After each use and before prolonged storage lubricate the equipment with approximately 1.5m1 of oil directly down the air inlet.

Assembly

• Note: Disconnect from the air supply before carrying out adjustment, servicing or maintenance.

• WHIP HOSE (Fig.1.):
  To connect the angle grinder to an air line a ¼” BSP male thread whip hose will be required. Wind a length of PTFE tape around the thread before securing the hose in place. The connection must be firm for an airtight union.
  Draper Stock No.54438
  Draper Stock No.63389.
  

• NOTE: Due to the rotating air inlet feature a spanner will be required to hold the inlet while securing the whip hose.

• GUARD (Fig.2.):
  The guard comes pre-assembled only requiring adjustment to suit the application. For comfort, it may be necessary to rotate the guard. Loosen locking bolt A. When adjustment is complete tighten locking bolt A to secure.
  

• WARNING: Never attempt to operate this machine without the guard securely fitted and correctly positioned’. Safety goggles must be worn in addition to using the guard.

• **FITTING/REPLACING ACCESSORIES (NOT SUPPLIED) (Fig.3.):

**

• WARNING: Selection of the correct accessory, suitable for the intended application is vital. Seek guidance if uncertain of selection.
  Prior to mounting an abrasive wheel ensure the expiry date has not exceeded rendering it potentially hazardous.

• VISUAL INSPECTION:
  Prior to fitting, abrasive wheels shall be subject to a visual inspection. Damaged abrasives shall be destroyed.

• WARNING:
  The rated (no-load) revolutions per minute of the tool must not exceed the speed capacity of the proposed accessory. Please refer to the accessory manufacturer’s instructions for information. Hold the spindle B securely with 19mm spanner. Remove the locking bolt C with the 4mm hex. key.

• NOTE: The locking bolt has a left hand thread and must be turned clockwise to loosen.

• With the locking bolt fully removed and the spindle still secured, remove the arbor bolt D with the 14mm spanner.
  NOTE: The arbor bolt has a standard right hand thread and must be turned anti-clockwise to loosen.

• Clean the flanges and spindle prior to fitting any accessories.

• Pass the arbor bolt (with washer E fitted) through the abrasive wheel and into the spindle.
  Tighten the arbor bolt D before refitting the locking bolt C.

• INSPECTION:
  Each time after mounting, the abrasive wheel shall be test run for a reasonable time. The specific maximum operating speed of the wheel shall not be exceeded.

• NOTE: When fitted, ensure the accessory is correct but more importantly fully secure on the spindle.

Operation and USE

• TRIGGER (Fig.4.):
  Due to the risk of unintentional starting the angle grinder requires two separate and dissimilar actions to power the tool. Pivot the trigger release lever F forward. This allows the trigger B to be pulled in towards the body of the grinder.

• WARNING:
  Do not set the machine down until the spindle has completely stopped.

NOTE:
During use, keep clothing out of the line of any sparks formed. Sparks from metal cutting can set fire to many types of clothing after a short delay. The risk is less if your clothing is made of wool, or flame retardant treated cotton.

• DUST: A correct fitted dust mask, suitable for the activity and in accordance to the relevant standard, must be worn.

• DIRECTION OF ROTATION (Fig.5.):
  The direction of rotation can be altered to ensure the sparks generated from cutting can be directed away from the user regardless of positioning dictated by access to the workpiece.
  

• CUTTING (Fig.6.):
  When performing cutting-off operations do not incline the machine as this can lead to the abrasive wheel becoming jammed, damaged or excessively and abnormally worn.
  Only use abrasives specifically designed for this task.
  

• WARNING:
  As the cutting-off wheel wears during use, its diameter reduces. This reduces the peripheral speed and the cutting efficiency. This results in increased load on the machine which if continued will damage the motor. Ensure that the diameter of the wheel is within 25% of its original size.

• IMPORTANT:
  Excessive pressure on the machine does not result in a higher abrasive efficiency. Excessive pressure increases wear and tear on the accessory and will damage the cut-off tool, invalidating the guarantee. In extreme cases this can cause the wheel to shatter and cause serious injury.

• AIR FLOW ADJUSTMENT (Fig.7):
  The air flow can be governed by adjusting screw H which controls the running speed. This adjustment of the running speed can more readily be made on the in line regulator (if fitted) from the air supply.
  

MAINTENANCE

Regular maintenance will help keep the cut-off tool in a safe working condition.

DAILY:

• Before connection to the air supply drain the compressor reservoir, air lines and water trap of condensate. Check the level of the in line lubricant and adjust as necessary. Adjust the air line level correct for the tool.
• Inspect the abrasive and guard.
• Lubricate the tool with approximately 1.5ml of oil directly down the air inlet.

EVERY 48HR RUNNING TIME:

• Inspect the spindles, threads and clamping devices in respect of wear and tolerances for location of abrasive product.
