GB
• Some building materials contain toxic substances. Always use adequate
breathing and skin protection when operating this machine in a dusty
environment, especially if you expect toxic substances to be present,
or if you are unaware about the composition of the materials to be
worked on. Always adhere to laws and regulations when disposing of
toxic substances
• Only use extension leads of a suitable type that is approved for the
environment you are working in. Conductors must be of adequate
cross section, as the machine may otherwise operate at reduced
performance, and the extension lead may overheat. Check the
extension cord for damage before every use, at the same time as
checking the machine's main power cable. Damaged extension cords
MUST NOT be used and need to be replaced. Always fully unwind the
extension lead or cable reel, as it will overheat otherwise
• In some situations you may want to power your machine off a
construction site generator or transformer. This is generally possible;
however, ensure that the power rating of the power source is at least
double the power rating of this machine, and that the power supplied is
of compatible voltage/frequency (see 'Specifications'). Ensure that the
power source is equipped with automatic voltage regulation and surge
protection, as voltage peaks may result in tool damage.

Before Use

Adjusting the side handle
Note: The included side handle features a vibration-reducing, dampening,
ridged rubber grip. Always make use of this handle when operating this
machine.
• When in use, always hold the tool firmly by the Main Handle (1) and
Side Handle (5)
• The side handle can be rotated to best suit the work to be performed:
1. Loosen the plastic knob of the handle clamping mechanism
2. Rotate the side handle in the position most suitable for the task at hand
3. Tighten the plastic knob firmly to lock the side handle in place
Note: For storage in the included metal case, the side handle needs to be
folded in line with the main handle.
Installing hex fitting steels
WARNING: Only use this tool with good quality 30mm or 1-1/8"
diameter steel bits with hex fitting. Do not force other types of steels to fit.
Misuse of this tool could cause permanent damage, and may invalidate
your warranty.
1. Ensure the flat portion on the shank of the steel bit is facing towards the
Tool Retainer (6), and that the tool retainer is in the unlocked position
2. Insert the steel into the Tool Holder (7), ensuring the groove in the steel
aligns with the tool retainer
3. Pull out the spring-loaded tool retainer and rotate 180° into the locked
position to secure the bit (Fig. A)
4. Test that the steel has been correctly installed by trying to pull it out of
the tool holder

Operating Instructions

WARNING: Always wear adequate personal protection equipment when
setting up and operating this machine.
IMPORTANT: Check the oil level and the power cord before each use
(see 'Maintenance').
WARNING: Heavy breaking equipment produces larger amounts of
vibrations. It is advisable to wear thick vibration-reducing gloves when
operating this tool.
Switching on and off
• Grip the breaker firmly by both the Main Handle (1) and the Side
Handle (5)
• To start the breaker, squeeze the On/Off Trigger Switch (2)
• Once the on/off trigger switch is depressed, the Lock-on Switch (3)
can be engaged
• To stop the breaker, release the on/off trigger switch
Note: If the lock-on switch was engaged, depress the on/off trigger switch
again and release, to disengage the lock-on mechanism and switch off
the machine.
Notes:
• Applying excess pressure does not result in faster or more efficient
breaking
• Best breaking results can be obtained by only applying slight pressure
to the tool, enough to keep the automatic clutch engaged and the
hammer action working
• If the pressure applied to the breaker has a noticeable effect on the
speed, reduce the pressure
• Overloading the breaker will reduce its service life
Accessories
• A range of accessories for your electric breaker, including replacements
steel bits, is available through your authorised Silverline dealer.
