RUPES GM62N Angular Grinders

TECHNICAL DATA

GENERAL WARNINGS
All instructions concerning safety and the prevention of industrial accidents can be found in file SAFETY INSTRUCTIONS, that forms integral part of this documentation. This INSTRUCTION MANUAL only contains additional information that specifically explain how to use the machine.

SPECIFIC USE
This tool is designed to be used as grinder. Refer to all the safety warnings, instructions, illustrations and specifications supplied with the tool. Failure to follow all the instructions provided below may result in electric shocks, fires and/or serious injuries.
Theuse of this tool for smoothing, metal brushing and polishing operations is not recommended. Its use for applications other than those for which it has been designed may lead to hazardous situations and cause injuries to people.
Do not use accessories that are not specifically designed for the intended use of the tool or that have not been recommended by the manufacturer. The fact that an accessory can be fixed to the tool does not imply that it can be used safely.

The rated speed of accessories must be at least equivalent to the maximum speed of the tool. If operated at a greater speed than the rated one, accessories may break and cause the ejection of chips.
The external diameter and thickness of accessories must be appropriate to guarantee the protection and safety of the tool. Accessories with incorrect dimensions cannot be adequately protected or controlled.

The configuration of the cutting/grinding wheels or any other accessory must perfectly adapt to the tool spindle. Accessories with holes that cannot be aligned with the fitting components on the tools will cause unbalance, excessive vibrations and may be difficult to control.
Do not use an accessory if damaged. Before use, inspect all the accessories, like the abrasive cutting/grinding wheels, in order to verify that they are not cracked or splintered. If the tool or accessory has fallen, verify that they are not damaged and, if necessary, replace it with a new one. After inspecting or installing an accessory, move to a safe distance with any other person present and operate the tool at maximum speed without load for one minute. Damaged accessories generally break during this test period.

WARNINGS SPECIFICALLY RELATED TO GRINDING AND ABRASIVE CUTTING OPERATIONS
Use only the type of cutting/grinding wheels recommended for your tool and the protection specifically designed for the selected cutting/grinding wheel. Cutting/grinding wheels not designed to be used with the tool cannot be adequately protected and are unsafe.
The protection must be solidly fixed to the tool and placed in the safest position possible so as to minimise the potential risk of contact between the operator and cutting/grinding wheel. The protection is designed to protect operators from the ejection of fragments in case of breakage and from accidental contacts with the grinding wheel.
Cutting/grinding wheels must be used for the recommended applications only. For example do not use the cutting side of the wheel for grinding operations. Abrasive cutting wheels may break because they are designed to be used for peripheral grinding operations and for the application of lateral forces.
Always use the cutting/grinding wheels with undamaged flanges and verify that their shape and dimensions are appropriate for the selected cutting/grinding wheel. The purpose of flanges is to support the cutting/grinding wheel and reduce the potential risk of breakage.
Flanges for cutting wheels may be different from those of grinding wheels. Do not use grinding/cutting wheels that have been fitted on larger tools. These cutting/grinding wheels are unsuitable because of their higher speed as compared to that of smaller tools and could therefore cause explosions.
Do not “stall” the cutting wheel or apply an excessive pressure. Do not attempt to increase the cutting depth. The application of a high pressure on the cutting wheel increases the load and the risk of torsion and bending during cutting, with the consequent risk of rebound forces or breakage.
Do not stand in line with the cutting/grinding wheel or behind it while it is rotating. When the cutting/grinding wheel moves away from the operator’s body during operation, the rebound force may push the revolving cutting/grinding wheel and the tool towards the operator.
If the cutting/grinding wheel bends or the cutting operations stops for any reason, disconnect the tool from the power supply and keep it still until the cutting/grinding wheel has come to a full stop. Do not attempt to remove the cutting wheel while it is moving because this could produce a rebound force. Identify the cause of the problem and perform the necessary corrective actions to prevent the problem from reoccurring.
Do not resume the cutting operation. Resume the cutting operation only when the cutting wheel has reached its maximum speed. The cutting wheel may stall, lift or produce a rebound force if the tool is restarted when the work piece is present.
Always use appropriate supports for panels or large work pieces in order to minimise the risk of interlocking and rebound forces. Large work pieces tend to bend because of their weight. Supports must therefore be placed under the work piece, close to the cutting line and to the edge of the work piece on both sides.
Pay particular attention when cutting “pockets” on existing walls or other areas with limited visibility. The projecting cutting wheel may cut gas or water pipes, electrical cables or other objects and thus produce a rebound force.

STARTING UP
Before starting-up the tool, ensure that:

• the packaging is complete and does not show signs of having been damaged during sto-rage or transport;
• the tool is complete; check that the number and type of components comply with that re-ported in this instruction booklet;
• the power supply and socket outlet can support the load reported in the table and that in-dicated on the tool identification plate reproduced and explained on page 11.

ASSEMBLING THE TOOL

• Screw the auxiliary handle (6) in one of the holes on the gearbox, the handle can be mounted on the left or right of the tool body.
• Fit the guard on the body of the tool using the collar (8).
  Lock it in position by tightening the screw.
  The guard must be mounted level with the handle.

FITTING ABRASIVE WHEEL

1. Insert the spacer (9);
2. insert the abrasive wheel;
3. screw and tighten the lock nut (10) using the pin wrench, preventing the spindle form moving using the 17 mm. spanner or the spindle locking button (GM62N only).

BEFORE STARTING THE TOOL

Ensure that:

• the power supply conforms with the characteristics of the tool;
• the power supply cable and plug are in perfect condition;
• the ON/OFF switch works properly though with the power supply disconnected;
• the spindle locking button (GM62N) (4) is released (rotate the abrasive wheel by hand for at least one revolution);
• all the parts of the tool have been assembled in the proper manner and that there are no signs of damage;
• the ventilation slots are not obstructed.

STARTING AND STOPPING

• Starting: push the switch block (3) forward towards the body of the machine and simultaneously push the switch lever (2) up (fig. 4) in order to lock the switch in operating position.
• Stopping: push the switch lever (2) up in order to release the switch block (3).

TEST RUN
Start the tool and check that there are no unusual vibration, no dispatching of the wheel. Otherwise switch-off the tool immediately and eliminate the cause.

FITTING AND REPLACING ABRASIVE WHEELS

• GM62N
  Lock the wheel spindle by pressing button (4), while at the same time rotating thewheel until it locks position. Unscrew the locking ring using the pin wrench, replace the wheel, re-tighten the locking ring. Unlock the wheel spindle by releasing the buttonand rotate the wheel by hand to ensure that it runs freely.
  WARNING!: never press the wheel spindle locking button until the tool has stopped moving and is perfectly stationary; the gear box or the push button pin could be broken and the guarantee would be invalidated.

• GM62 – GM81 – GL41 – GL51
  Lock the wheel spindle by inserting the 17 mm spanner in the nocth in the spindle between the wheel and the gearbox. Unscrew the locking ring using the pin wrench, replace the wheel, re-tighten the locking ring.
  Tools other than those mentioned must not be used for slackening or tightening purposes.

USABLE ABRASIVE WHEELS

• GM81N – GL51N
  Depressed centre Ø 178 mm.
