2. Power switch
Ensure that the power switch is in the 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.
3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Installing Tools
CAUTION
Be sure to switch power OFF and disconnect the
plug from the receptacle to avoid serious trouble.
NOTE
When using tools such as bull points, cutters, etc.,
make sure to use the genuine parts designated by
our company.
(1) Clean the shank portion of the tool.
(2) As shown in Fig. 1, pull grip (A) in the direction of
A, and insert the tool into a hole of the front cap.
(3) Adjust the groove position while turning the tool, and
furthermore insert it until it hits the end of the hole.
(4) Return grip (A) to its original position, pull the tool
and make sure it is locked completely (Fig. 2).
5. Deciding Working Position of Tool
The tool can be turned every 30 degrees and can
be fixed at the position of 12 steps.
(1) As shown in Fig. 3, if the grip (A) is turned in the
direction of B in a state where the grip (B) is
pushed in the direction of A, the blade angle can
be changed freely to any desired position.
(2) Release grip (B) and turn the tool, and make sure
that it is locked completely.
6. Removing Tool
As shown in Fig. 1, pull grip (A), and pull out the
tool.
CAUTION
Be sure to grip the handle and side handle during
work. Do not hold by the grip (A) during work. If
you pull it by mistake, the bull point could jump out.
7. Move the side handle
The side handle can be fixed at any desired position;
360 degrees, and can also be fixed at any position
in the back-and-forth direction.
(1) Loosen the handle by turning the grip in the direction
of A as shown in Fig. 4.
(2) Adjust it to a position where vertical (up-and-down)
operation can be facilitated as illustrated in Fig. 5,
Fig. 6, and Fig. 7.
(3) Turn the grip in the direction of B and fix the
handle.
8. Select the number of strikes (applicable only to
H60MRV) (Fig. 8)
CAUTION: Do not make any adjustment of the dial
during operation. Holding the main
body with one hand can swing you
around, resulting in an injury.
This machine has an electronic controlled circuit
built-in, enabling stepless regulation of the number
of strikes. Make the most of this machine by
adjusting the dial according to the working contents;
chiseling, demolishing, or the quality of the material
to be chiseling or demolishing.
The scale ”1” of the dial is for the minimum speed
with 930 strikes per minute, and the scale ”6” is
for the maximum speed with 1650 strikes per minute.
HOW TO USE THE DEMOLITION HAMMER
(Fig. 9)
1. After placing the tip of the tool on concrete surface,
switch ON.
The switch can be turned ON if the trigger is pulled
and OFF when it is released.
If the stopper is pressed while the trigger for the
switch is pulled, even if your finger is released from
the trigger, the switch remains ON - convenient for
continuous operation.
To turn the switch OFF, pull the trigger again, and
then the stopper comes off.
2. By utilizing the empty weight of the machine and
by firmly holding the demolition hammer with both
hands, one can effectively control the subsequent
recoil motion.
Proceed at a moderate work-rate, the use of too
much pushing force will impair efficiency.
CAUTION
After long time of use, the cylinder case becomes
hot. Therefore, be careful not to burn your hands.
GREASE REPLACEMENT
This machine is of fully oil sealed construction to protect
against dust incursion and to prevent lubricant leakage.
This machine can be used without grease replenishment
for an extended period of time. However, perform the
grease replacement to extend the service life. Replace
the grease as described below.
1. Grease Replacement Period
You should look at the grease when you change
the carbon brush (See item 4 in the section
MAINTENANCE AND INSPECTION).
Ask for grease replacement at the nearest Hitachi
Authorized Service Center.
In the case that you are forced to change the grease
by yourself, please follow the following points.
2. How to replace grease
CAUTION
Before replacing the grease, turn the power off and
pull out the plug from the receptacle.
(1) Remove the crank case cover and the crank cover
and wipe off the old grease inside (Fig. 10).
(2) Supply 80 g (the standard volume to cover the
connecting rod) of Hitachi Electric Hammer Grease
A in the crank case.
