Assembly and disassembly of work tools (III)
Work tool in the form of a chisel, fl at chisel or punch is locked in the chuck by means of a rotating lock.
Pull off the lock of tool chuck and turn it 180 degrees so that the lock does not interfere with sliding in and out a work tool to and
from the chuck.
Hexagonal chuck on one wall has a groove that allows turning the chuck’s lock and locking the work tool in the chuck. Slip the
work tool into the chuck so that the groove is at the level of a lock. Then pull off the lock of tool chuck and turn it 180 degrees so
as to lock the possibility of sliding out the work tool from the chuck. Make sure of it by grabbing the tool and trying to slide it out of
the chuck. If the attempt is successful, repeat the work tool assembly procedure.
PRODUCT USE
Before starting the work make sure that the housing and connecting cable with a plug are not damaged. If any damage is found,
it is forbidden to continue the work!
Preparations
Select proper work tool: punch or chisel.
Clean the tool, apply a thin layer of grease on the chuck of selected tool.
Insert the work tool into the tool chuck of the product.
Insert the cable plug into the mains socket.
Put on hearing protectors, eye protection, work gloves.
Starting and stopping the product
Take a posture guaranteeing your balance, grab the hammer with both hands and having made sure that the work tool does not
touch anything, start the product by pressing and holding down the switch with your fi nger (IV).
Hold the tool in this position for several seconds to allow grease reaching all the elements of the drive mechanism and check at
the same time whether the product shows any signs of abnormal operation. Too much noise, vibration level too high, suspicious
odour or emergence of smoke. If no signs of abnormal operation are observed, the product may be used.
After completion of work, switch off the hammer by releasing the pressure on the switch.
The switch may be locked in the ON position, which may be useful during long-term operation. In order to lock the switch, press
the lock button with the switch pressed (IV). Lock is released by pressing the switch.
Working with product
It is recommended that in the initial period of use, operation of tool is not too intensive, it will allow mechanical parts to run-in. It is
also recommended to use longer breaks in order to cool the hammer. As the elements inside the hammer run in, you can increase
the intensity of operation and shorten the breaks needed for cooling the tool.
Note! Sometimes it may happen that the hammer fails to transfer impact to the work tool, even though the engine works. Usually
this may be caused by too thick oil. If the product is used at low temperature, let it work for approx. 5 minutes to warm it up.
Lean the work tool against work surface, grab both grip handles of the hammer and start it with the switch. If the work tool has
failed to start, push the hammer towards the work surface. This does not result from incorrect operation but the protection against
operation with no load.
During the work, apply only pressure necessary for the correct operation of the tool. Applying too much pressure on the work tool
may cause damage to the work tool and hammer drill mechanisms, and it will also reduce its effi ciency.
If the product is used to remove large-thickness surfaces, this operation should be carried out by layers. Each time, remove a
layer of small thickness.
Make regular breaks during the work.
Additional notes
Do not apply too much pressure on the processed material during operation and do not make sudden movements to prevent dam-
age to the work tool and drill. Make regular breaks during the work. Do not overload the tool, temperature of outside surfaces can
never exceed 60 °C. After completed work, turn off the drill, unplug the tool from the mains socket and carry out the maintenance
and inspection operations.
Declared total value of vibration was measured by means of standardized test method and can be used to compare one tool with
the other. Declared total value of vibration can be used in the initial exposure assessment.
Note! Emission of vibration when working with the tool may vary from the declared value, depending on how the tool is used.
Note! It is required to determine safety measures to protect the operator, which are based on the exposure assessment in real
conditions of use (including all elements of work cycle, such as for example time when tool is switched off or idling and time of
activation).
