Denzel RH-750-24 [9/28] Rotary hammer

ROTARY HAMMER

revolutions by more than 20% compared to idle leads to a signicant deterioration in engine cooling and

indicates overload;

• do not overheat external Electrical Rotary Hammer parts during long work. If there is an excessive heat, stop

working, let the Electrical Rotary Hammer work without load for 1-2 minutes for engine cooling, turn o the

engine and take a break until the gear housing become cool;

• do not allow the Electrical Rotary Hammer work when there is extraneous or uncharacteristic noise in the engine

or gear. When there are noises turn o the Electrical Rotary Hammer and contact an authorized service;

• turn o the Electrical Rotary Hammer with the switch before disconnecting from the power supply.

ATTENTION!

If during usage the Electrical Rotary Hammer unexpectedly shuts down work it is necessary:

1. To turn the power key to "o" immediately and disconnect the power cable from the outlet.

2. To inspect the tool and electrical cable for damage carefully. If damage is found, contact the

service center.

3. Check for mains voltage.

4. To carry out trial switch on by turning the switch key to the “on” position for 1-2 sec. If in the

presence of power in the mains the Electrical Rotary Hammer does not turn on, you need to

contact the service center.

At the end of the work:

• disconnect the Electrical Rotary Hammer from the mains, making sure the switch is in the o position;

• clean the Electrical Rotary Hammer and accessories from dirt;

• with a long break in work lubricate the box with a layer of conservation grease;

• periodically clean the ventilation holes with a soft brush and vacuum cleaner.

NOISE AND VIBRATION

Noise and vibration characteristics are given in the "Specications table".

The noise and vibration levels specied in this manual are measured by measurement method, prescribed in the

standard, and can be used to compare. However, if the Electrical Rotary Hammer is used for other work with the

use of working toolings, not provided by the manufacturer, or maintenance does not meet the requirements, then

the vibration level may be dierent.

ATTENTION!

Always use personal hearing protection.

MAINTENANCE

ATTENTION!

Before starting maintenance and adjustment of the Electrical Rotary Hammer unplug the power cord

from the power outlet. To ensure quality and safe functioning keep your tool and vents clean at all times.

• If you notice a decrease in impact energy, working tool speed of rotation or extraneous noise, it is necessary to

hand over the punch to the service center for its repair.

• Working tool maintenance. The use of the worn working tool reduces the eectiveness of the work and may

result in motor or gearbox failure, so you need to sharpen periodically or replace worn removable tools, as soon

as there is a need.

• Electric motor care. You must be especially careful with the electric motor, avoid getting liquids and objects

inside the case. Keep your ventilation holes clean, blow them regularly with compressed air or clean them with

a brush. When noticeable sparks appear, contact an authorized service center for diagnostics and replacement

of carbon brushes if necessary.
