Stock: Make sure there is no metal or other things to
block the connector after every dive and keep the brass
pin dry when storing.
A battery can be charged at any time without reducing its service
life. This is because the battery charger detects the charging
condition of the battery, and charges it with the optimum current
according to its temperature and voltage. This lengthens the
battery life and leaves it fully charged when stored in the charger.
Interrupting the charging procedure does not damage the battery.
1. Connect the mains plug of the battery charger to an electrical
outlet. A steady green light on the battery charger indicates
that the charger is ready for operation.
2. Press the battery charger’s connector into the socket on the
top of the battery pack. There is only one way to insert the
connector into the battery socket.
The battery begins charging as soon as it is connected to the

Tips for Use
♦Always put the bit in contact with the surface you’re working
on prior to pulling the trigger for maximum control.
♦Always hold the rotary hammer firmly and use moderate, even
pressure. Applying too much pressure, especially at lower
speeds, will cause the hammer to stall. Utilizing too little
pressure or uneven pressure can cause the bit to skip and slide
over the surface and/or prevent it from cutting through the
work surface.
♦Wipe the shanks of the bits clean prior to installation and
immediately after removing them from the rotary hammer.
Maintenance
Rotary Hammer Care
♦When working in cold weather or when operating the tool after
it has been stored for a long time, run the tool under no load
for several minutes. This lubricates the tool and warms it up. If
it is not properly warmed and lubricated, the rotary hammer
will be difficult to operate.
15

♦Blow air through the tool housing after every use to remove
dust.
♦Rinse the rotary hammer with fresh water after exposure to
salt water. The rotary hammer can be used in salt water, but
allowing salt to build-up on the tool shortens its lifespan.
♦Do not use solvents or cleaning supplies to clean the rotary
hammer. Fresh water and soft, lint-free cloths are all that are
necessary.
♦Post dive maintenance. :Water trapped inside the female
battery connection may corrode the terminals . Use
compressed air to flush out any remaining water trapped in the
3 large holes on the battery connection.
Servicing the Rotary Hammer
If your rotary hammer is damaged or faulty, have it repaired by an
authorized service technician.
Caution: Under no circumstances should the rotary
hammer be opened for repairs or any other purpose by
anyone other than an after-sales service technician
authorized by Nemo Power Tools. Opening the rotary
hammer invalidates the manufacturer warranty.
16

Transporting the Rotary Hammer
For maximum protection, always transport your rotary hammer
secured in its carrying case, with the battery removed.
The battery pack has effective protection against internal
over-pressure and short-circuiting, as well as devices preventing
violent rupture and dangerous reverse current flow.
The lithium-equivalent content in the batteries is below applicable
limit values. Therefore, the batteries are not subject to national or
international regulations pertaining to dangerous mediums, either
as individual components or when inserted into a power tool.
However, the regulations governing dangerous goods may be
relevant when transporting several batteries. In this case, it might
be necessary to comply with special conditions, such as those
governing packaging.
Disposing of the Rotary Hammer
At the end of its lifecycle, the rotary hammer, its accessories, and
packaging should be sorted for environmentally friendly recycling.
Do not dispose of the battery pack in household waste, fire, or
water. Battery packs should be collected, recycled, or disposed of in
an environmentally friendly manner.
