7. PRECAUTIONS IN SALES PROMOTION
In the interest of promoting the safest and most efficient use of the Model H 45SR Electric Hammer by all of our
customers, it is very important that at the time of sale the salesperson carefully ensures that the buyer seriously
recognizes the importance of the contents of the Handling Instructions, and fully understands the meaning of the
precautions listed on the Caution Plate attached to each tool.
7-1. Handling Instructions
Although every effort is made in each step of design, manufacture and inspection to provide protection against
safety hazards, the dangers inherent in the use of any electric tool cannot be completely eliminated. Accordingly,
general precautions and suggestions for the use of electric power tools, and specific precautions and suggestions
for the use of the Electric Hammer are listed in the Handling Instructions to enhance the safe, efficient use of the
tool by the customer. Salespersons must be thoroughly familiar with the contents of the Handling Instructions to
be able to offer appropriate guidance to the customer during sales promotion.
7-2. Caution Plate
The Model H 45SR unit is provided with a Caution Plate (illustrated below) which lists basic safety precautions in
use. Carefully ensure that the customer fully understands and follows these precautions before using the tool.

7-3. Grease Replacement
The striking portion and the speed reduction portion of the Model H 45SR respectively use different types of
grease. Grease replacement is required if the unit is disassembled for maintenance or O-rings become damaged
and worn as described in 7-4.
The striking portion uses special grease. If the striking portion (inside the cylinder crank case) is disassembled,
thoroughly remove all of the old grease from each part. On reassembly, insert 53 g (1.9 oz) of new grease into
the cylinder crank case (connecting rod side). Do not exceed the designated amount of grease. Excessive
grease insertion may cause reduced striking performance.
The speed reduction portion (inside the gear cover) uses Hitachi Motor Grease No. 29 (Code No. 930035). The
proper supply volume is 20 g (0.7 oz). Never use the striking portion special grease in the speed reduction
portion. Special grease would leak into the motor portion and cause subsequent trouble.
