Proper use of tool

This sander is designed for sanding all types of materials such as paints, metals, wood, stone, plastics, etc., using abrasives specially designed for this purpose. Do not use this sander for any other purpose than that specified without consulting the manufacturer or the manufacturer's authorized supplier. Do not use backing pads with an operating speed of less than 8 000 rpm free speed. Any maintenance or repair work requiring the motor housing to be opened may only be carried out by an authorized service center.

Battery and charger

• The battery pack is not fully charged out of the carton. First read the safety instructions and then charge your battery according to the instructions.
• For optimal charging capacity the battery should be charged at an ambient temperature between 18 °C (64 °F) and 24 °C (75 °F). To prevent damage to the battery pack, do not charge the battery pack where the air temperature is below 4 °C (32°F) or above 40 °C (104 °F).
  • To obtain the longest possible battery life, we suggest the following:
• Store and charge your battery in a cool area. Temperatures above or below normal room temperature will shorten battery life.
• Never store the battery in a discharged condition. Recharge it immediately after it has been discharged.
• All batteries gradually lose their charge. The higher the temperature, the quicker they lose their charge.

If you store your tool for long periods of time without use, recharge the battery every month. This practice will prolong battery life.

Charging procedure

• Connect the power cord to the charger, and then plug into an outlet before inserting battery pack. All three charging lights will be on for two seconds and then turn off.
• Insert the battery pack into the charger. The lights will start to flash within 30 seconds.
• During the charging process, the charging lights will indicate the status as follows:
• Three charging lights will flash in sequence during the charging process.
  – Fully charged, all three lights will remain on continuously.
• The charging process will last approximately 40 minutes for Mirka 10.8 V 2.0 Ah battery pack.

NOTE: This charger can only charge Mirka 10.8 V battery packs.

NOTE: Charging times may be longer depending on the surrounding temperature and battery conditions.

Charger diagnostics

The charger will indicate if:

• A battery pack is overheated. All three charging lights will flash. Remove the battery and allow it to cool down for 15–30 minutes and re-insert.
• A malfunction occurs in the battery or the charger. Two charging lights will flash. Remove the battery and allow it to cool down. Re-insert the battery pack into the charger. If two charging lights still flash, the battery or charger may require service.

How to get started

• When unpacking the tool, make sure it is intact, complete and has not been damaged in transport. Never use a damaged tool.
• Before use, check that the backing pad is correctly mounted.
  • Install the fully charged battery pack into the sander until it locks in place with a click.

Operating instructions

• The tool is intended to be operated as a hand-held tool. The tool can be used in any position.
• Select a suitable abrasive and secure it to the backing pad. Make sure the abrasive is centered on the backing pad.
• The sander can now be activated / turned on and started by pressing the switch trigger.
• The sander will run and stay in active mode as long as the trigger is pressed. After the trigger is released the sander will stop but continue to stay in active mode for a short time before it automatically deactivates / turns off.
• When sander is in active mode the right LED is green.
  • In active mode the left LED shows the battery status:

- Green: Battery charge level is OK.

- Flashing green/red: Battery charge level is weak.

- Red: Battery voltage too low. Sander is not operable.

• In active mode the max rpm can be adjusted by pressing rpm+ or rpm−, Figure 1. The rpm can be adjusted in steps of 4 000, 5 000, 6 000, 6 500, 7 000, 7 500 and 8 000 rpm.
• The rpm can be locked to prevent an accidental rpm change. Wait until the sander is not in active mode. Simultaneously press and hold both rpm+ and rpm− buttons and then pull the switch trigger. In order to unlock the tool, repeat same operation. If rpm+ or rpm− is pressed in speed lock mode the right led flashes red twice but no speed change occur.
• When sanding, always place the tool on the work surface before starting the tool. Always remove the tool from the work surface before stopping it. This will prevent gouging of the work surface due to excess speed of the abrasive.
• When sanding is finished, remove the battery from the sander by simultaneously pressing the button on both sides and removing the battery from the tool. Charge the battery.

Proper use of tool

This sander is designed for sanding all types of materials such as paints, metals, wood, stone, plastics, etc., using abrasives specially designed for this purpose. Do not use this sander for any other purpose than that specified without consulting the manufacturer or the manufacturer's authorized supplier. Do not use backing pads with an operating speed of less than 8,000 rpm free speed. Any maintenance or repair work requiring the motor housing to be opened may only be carried out by an authorized service center.

Battery and charger

• The battery pack is not fully charged out of the carton. First read the safety instructions and then charge your battery according to the instructions.
• For optimal charging capacity the battery should be charged at an ambient temperature between 18 °C (64 °F) and 24 °C (75 °F). To prevent damage to the battery pack, do not charge the battery pack where the air temperature is below 4 °C (32 °F) or above 40 °C (104 °F).
  • To obtain the longest possible battery life, we suggest the following:
• Store and charge your battery in a cool area. Temperatures above or below normal room temperature will shorten battery life.
• Never store the battery in a discharged condition. Recharge it immediately after it has been discharged.
• All batteries gradually lose their charge. The higher the temperature, the quicker they lose their charge.

If you store your tool for long periods of time without use, recharge the battery every month. This practice will prolong battery life.

Charging procedure

• Connect the power cord to the charger, and then plug into an outlet before inserting battery pack. All three charging lights will be on for two seconds and then turn off.
• Insert the battery pack into the charger. The lights will start to flash within 30 seconds.
• During the charging process, the charging lights will indicate the status as follows:
• Three charging lights will flash in sequence during the charging process.
  – Fully charged, all three lights will remain on continuously.
• The charging process will last approximately 40 minutes for Mirka 10.8 V 2.0 Ah battery pack.

NOTE: This charger can only charge Mirka 10.8 V battery packs.

NOTE: Charging times may be longer depending on the surrounding temperature and battery conditions.

How to get started

• When unpacking the tool, make sure it is intact, complete and has not been damaged in transport. Never use a damaged tool.
• Before use, check that the backing pad is correctly mounted.
  • Install the fully charged battery pack into the sander until it locks in place with a click.

Operating instructions

• The tool is intended to be operated as a hand-held tool. The tool can be used in any position.
• Select a suitable abrasive and secure it to the backing pad. Make sure the abrasive is centered on the backing pad.
• The sander can now be activated / turned on and started by pressing the switch trigger.
• The sander will run and stay in active mode as long as the trigger is pressed. After the trigger is released the sander will stop but continue to stay in active mode for a short time before it automatically deactivates / turns off.
• When sander is in active mode the right LED is green.
• In active mode the left LED shows the battery status:
• Green: Battery charge level is OK.
• Flashing green/red: Battery charge level is weak.

• Red: Battery voltage too low. Sander is not operable.

• In active mode the max rpm can be adjusted by pressing rpm+ or rpm−, Figure 1. The rpm can be adjusted in steps of 4,000, 5,000, 6,000, 6,500, 7,000, 7,500 and 8,000 rpm.

• The rpm can be locked to prevent an accidental rpm change. Wait until the sander is not in active mode.
  Simultaneously press and hold both rpm+ and rpm- buttons and then pull the switch trigger. In order to unlock the tool, repeat same operation. If rpm+ or rpm- is pressed in speed lock mode the right led flashes red twice but no speed change occur.
• When sanding, always place the tool on the work surface before starting the tool. Always remove the tool from the work surface before stopping it. This will prevent gouging of the work surface due to excess speed of the abrasive.
• When sanding is finished, remove the battery from the sander by simultaneously pressing the button on both sides and removing the battery from the tool. Charge the battery.
