(Although the oil tank is built in, it contains only
a small volume of oil when shipped from the Hitachi
Works.)
5. Tool Mounting:
CAUTION:
Be sure to switch OFF and disconnect the attachment
plug from the receptacle to avoid a serious accident.
NOTE:
For tools such as a bull point and a cutter, use only
HiKOKI
Hitachi genuine parts.
(1) Clean, then smear the tool shank with grease or
machine oil. (Fig. 1)
(2) Rotate the stop lever 180° in a clockwise direction
while pulling it toward you. Next, insert the tool
shank into the hexagonal hole on the front cover.
(Fig. 1)
(3) Clamp the tool by turning the stop lever by half
a turn in the opposite direction. (Fig. 2)
NOTE:
When removing the tool, follow the above
procedures in reverse.
HOW TO USE THE DEMOLITION HAMMER
1. Pull the trigger switch after applying the tip of the
bit to the crushing position.
In some cases, it is necessary to punch the tip of
the bit against the crushing position forcibly in
order to begin the striking motion.
This is not due to malfunction of the tool. It means
that the safe guard mechanism against no-load
striking is working.
2. Operate the tool by utilizing its empty weight. The
performance will not be better even if the tool is
pressed or thrust forcibly against the work surface.
Hold the tool with a force just sufficient to counteract
the reaction. (Fig. 3)
CAUTION:
Sometimes the tool does not begin the striking
motion even when the motor rotates because the
oil has become thick.
If the tool is used at low temperatures or if it is
used after a long time idle, the tool should be used
running in for five minutes in order to warm it up.
OIL FEEDING
CAUTION: Prior to oil feeding, always disconnect the plug
from the receptacle.
Since an oil chamber is built in this Demolition Hammer,
it can be used for approximately 20 days without
replenishing lubricationg oil, assuming that the Hammer
is used continuously 3 – 4 hours daily.
Feed oil into the oil tank as described below before using
this Demolition Hammer. (See Figs. 4 and 5)
1. Just before no oil is visible in the oil gauge window
when the power tool is held upright, feed oil without
fail.
2. Before feeding oil, use the provided wrench to
remove the oil gauge.
Be careful not to lose the rubber packing attached
below the oil gauge.
3. Check the oil level once a day, confirming that oil
is filled.
4. After feeding oil, securely clamp the oil gauge.
NOTE:
HiKOKI
As an optional accessory, oil for the Demolition
Hammer (one liter) is sold separately. Use this oil
when oil in the tank is depleted. Shell Oil Co.
ROTELLA #40 (engine oil) can also be used. This
oil is sold as Shell gasoline stations most anywhere.
MAINTENANCE AND INSPECTION
CAUTION:
Be sure to swith OFF and disconnect the attachment
plug from the receptacle to avoid a serious accident.
1. Inspecting the tool
Since use of a dull tool will degrade efficiency and
cause possible motor malfunction, sharpen or
replace the tool as soon as abrasion is noted.
2. Inspecting the mounting screws:
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
water.
4. Inspecting the carbon brushes (Fig. 6)
The Motor employs carbon brushes which are
consumable parts. When they become worn to or
near the "wear limit", it could result in motor trouble.
When an auto-stop carbon brush is equipped, the
motor will stop automatically. At that time, replace
both carbon brushes with new ones which have the
same carbon brush Numbers shown in the figure.
In addition, always keep carbon brushes clean and
ensure that they slide freely within the brush holders.
5. Replacing carbon brushes:
Loosen the screw (Hexagon socket hd. bolts M4×12)
of the cap covers, then remove the cap covers. After
removing the brush caps, the carbon brushes can
be removed.
After replacing the carbon brushes, tighten the brush
caps, then mount the cap covers securely.
