may invalidate your warranty.
1. Ensure the flat portion on the shank of the steel bit is facing towards the Tool Retainer (2),
and that the Tool Retainer is in the unlocked position
2. Insert the steel into the Tool Holder (1), 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 . I)
4. Test that the steel has been correctly installed by trying to pull it out of the Tool Holder
Operation
WARNING: Always wear adequate personal protection equipment when setting
up and operating this tool .

• If the pressure applied to the Electric Breaker has a noticeable effect on the speed,
reduce the pressure
• Overloading the Electric Breaker will reduce its service life

General inspection
• Regularly check that all the fixing screws are tight. They may vibrate loose over time
IMPORTANT: Due to the aggressive nature of this tool, the power cable may become damaged
or worn through contact with sharp masonry. Check the cable before each use and replace if worn
or damaged. Do not use the tool if the cable is damaged in any way. Have the cable replaced by an
authorised Silverline service centre .
Checking the oil level
IMPORTANT: Although your Electric Breaker is pre-filled with high quality machine oil at the factory,
it is important to CHECK THE LEVEL BEFORE FIRST USE and top up if required. See "Specifications"
for the correct oil type.
IMPORTANT: The oil should be changed after 60 hours of use by a qualified technician or an
authorised Silverline service centre .
WARNING: Always ensure that there is sufficient oil in the tool prior to use.
1. Place the tool on its side so that the Oil Level Indicator (8) is shown vertically on the side
of the tool. Wait a few seconds for the oil to collect
Note: The oil level can also be checked when the tool is held vertically.
2 . Check the oil level in the Oil Level Indicator
Note: If the oil level is low, i.e. the level is below half of the Oil Level Indicator,
the oil needs to be topped up .
Topping up the oil
1. Place the tool down so the Oil Level Indicator (8) is on top facing up
2. Unscrew the Oil Level Indicator (8) using the Spanner supplied (Fig. III)
WARNING:Be careful not to lose or damage the seal.
3. Top up the reservoir with the recommended oil (see "Specifications"),
to at least 1/2 of the Oil Level Indicator
Note: For heavy duty use, fill the oil level to at least 3/4 of the Oil Level Indicator
WARNING: DO NOT overfill. The level should be visible in the Oil Level Indicator.
4 . Replace the Oil Level Indicator
5 . Place the tool on its side and check the level
6. Correct the fill level if necessary
Checking/replacing the carbon brushes
Important: Check the carbon brushes every 100 hours of use.
• Over time the carbon brushes inside the motor may become worn
• Excessively worn brushes may cause loss of power, intermittent failure, or visible sparking
Note: There are 2 brushes located either side of the housing. Repeat the below procedure
for both brushes
1. Remove the Brush Access Cap (7) by removing the 2 Phillips screws
2. Unscrew the Brush Retaining Cap (Fig. II) and remove the Brush
3. Inspect the Brush for wear
4. If worn below 6mm replace with a new Brush. Ensure the brush is inserted with
the spring at the top (Fig . II)
Note: If either brush is worn, they should both be replaced.
5 . Replace the Brush Retaining Cap
Note: The Brush Retaining Cap is used to apply pressure to the Brush via the spring .
This will result in pressure being applied to the Brush Retaining Cap whilst you attempt to
screw it back into its location.
6 . Replace the Brush Access Cap
Note: Alternatively, have the machine serviced at an authorised Silverline service centre .
