CAUTION
• Always install the battery cartridge fully until the red indicator cannot be
seen. If not, it may accidentally fall out of the tool, causing injury to you or
someone around you.
• Do not install the battery cartridge forcibly. If the cartridge does not slide in
easily, it is not being inserted correctly.
Battery Protection System
The battery is provided with a protection system for automatically turning
output OFF to extend the life of the battery. This occurs due to the battery
protection system, and is not a malfunction.
Operation panel Battery indicator
• If the battery is about to run out during use of the product, the battery
indicator on the operation panel lights. If use is continued in this state, the
laser beam will go out.
• The battery indicator may indicate different remaining capacity from
actual capacity depending on conditions of use, air temperature and other
factors.
NOTE: To ensure prolonged battery use
• Do not recharge fully charged batteries.
• Charge batteries within an ambient temperature range of 10°C to 40°C (50°F to
104°F).
• We recommend inserting batteries that have heated up immediately after use, for
example, into the charger and allowing them to cool down before charging them.
