Maintenance - Ryobi ERH710RG Owner's Operating Manual

MODE SELECTOR
See Figure 6.
Your hammer drill is equipped with a hammer stop facility
for smooth drilling.
 To deactivate the hammer action, turn the mode
selector clockwise to .
 To reactivate the hammer drill action, the mode
selector has to be reset to
You can use the selector to change modes even when
the hammer drill is operating (at low speed). The selected
mode is only activated once the variable switch is pressed
to start the tool.
NOTE: Anti-clockwise rotation during impact drilling
damages the drill bit. Deactivate the hammer action when
using a diamond drill bit.
ROTATION STOP
The mode selector on the ERH710RG features a third
position, Rotation Stop Mode
of the tool whilst maintaining the hammer action. This
feature enables the tool to be used for chiselling, when
fi tted with the appropriate bit.
REVERSING THE DIRECTION OF ROTATION
The direction of rotation of the drill may be changed by the
use of the reverse lever on the switch, situated above the
trigger. The position of this should only be changed when
the drill is at a standstill.
The reverse lever has two positions:
 Clockwise rotation: Set the reverse lever to the right
position.
 Anti-clockwise rotation: Set the reverse lever to the left
position.
When hammer drilling, you do not need to force the
drill. Too much pressure will place unnecessary load on
the motor. Check the drill bits regularly. Re-sharpen or
replace blunt drill bits.
LIVE TOOL INDICATOR
This tool features a live tool indicator which illuminates as
soon as the tool is connected to the supply. This warns the
user that the tool is connected and will operate when the
switch is pressed.

MAINTENANCE

When servicing, use only identical Ryobi replacement
parts. Use of any other parts may create a hazard or
cause product damage.
 Unplug the hammer drill before making any adjustment,
servicing or cleaning the tool.
 Keep your machine clean at all times.
 Never use caustic agents to clean the plastic parts.
 At the end of your work, to prevent dust deposits, use
compressed air (maximum of 3 bars) to clean out the
ventilation slots.
 Check the carbon brushes regularly (dirty or worn
carbon brushes result in excessive sparking and
speed faults).
