7. PRECAUTIONS IN SALES PROMOTION

In the interest of promoting the safest and most efficient use of the Model H 45MR 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.

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.

The Model H 45MR 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.

The striking portion and the speed reduction portion of the Model H 45MR respectively use different types of

grease. Grease replacement is required if the unit is disassembled for maintenance of 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.
