Maintenance - SPARKY Professional K 2050 Notice Originale

PRIOR TO INITIAL OPERATION
▪ Always check the position of ON/OFF switch. The
power tool must be connected to the power supply
socket only when this switch is in OFF position. If the
plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.
▪ Make sure the cord and the plug are in order. If the
replacement of the supply cord is necessary, this has
to be done by the manufacturer or his agent in order
to avoid a safety hazard.
▪ Switch off and unplug the machine prior to any pro-
cedure on the power tool or in case of mains drop
out.
▪ In case of work area remote from the power source,
use as short as practicable extension cord with prop-
er cross-section.
▪ Make sure the auxiliary handle is properly mounted
and securely fastened.
INSTALLING AND REMOVING BITS

chine prior to any procedure on the power tool.
1. Clean and then smear the tool shank with grease or
machine oil (Fig. 1).
2. Pull the tool retainer lever (2) toward yourself.
3. Rotate 180° clockwise the tool retainer lever (2) while

4. Next, insert the tool shank into the hexagonal tool
holder (1) on the front cover (3).
5. Clamp the tool by turning the tool retainer (2) by half a

To remove the bit, follow the above described proce-
dures in reverse order.

OPERATING THE BREAKER
▪ Insert the plug into the socket.
▪ Apply the tool tip at 80–100 mm from the edge of the
material to be processed and press the trigger switch
(6).
▪ Start operating at 70°–80° to the surface and guide
the tool tip to the edge. Then change the angle to 90°
and break the processed material.
▪ Operate the machine by utilizing its empty weight
to achieve optimum performance. Insufficient force
shall cause tool rebound. Too high pressure against
the surface shall decrease efficiency.
In some cases, it is necessary to punch the tool tip
against the crushing position forcibly in order to actuate
the striking motion. This is not due to malfunction of the
tool. It means that the safeguard mechanism against no-
load striking is working.
WARNING: Sometimes the striking motion
does not start even when the motor rotates because
the grease has become thick. If the breaker is oper-
ated at low ambient temperature or after storage, let
the machine run for five minutes in order to warm up.
▪ Turn the tool at regular intervals to achieve uniform
wear and aid self-sharpening.

Maintenance

WARNING: Always ensure that the tool is
switched off and unplugged before attempting to perform
inspection or maintenance.
REPLACING AND ADDING LUBRICANT
The power tool is delivered with proper amount of lubri-
cant. Do not add lubricant to a newly purchased breaker.
Check the level of lubricant and replace it every 6 months
after initial operation. These activities shall be performed
in authorized SPARKY service centres ONLY.
Preventive care will prolong the life of your power tool.
If the impact energy begins to decrease or the bit shank
is dry and unlubricated during operation, contact author-
ized SPARKY service centre to check lubricant level
and/or quality of fast-wearing parts.
