7. PRECAUTIONS IN SALES PROMOTION

In the interest of promoting the safest and most efficient use of the Models H 60MR and H 60MRV Demolition

Hammers 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 Demolition 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.

Each unit of the Models H 60MR and H 60MRV 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.

For Australia, New Zealand and India

For the U.S.A. and Canada

The striking portion and the speed reduction portion of the Models H 60MR and H 60MRV 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 case and crank case) is disassembled, thoroughly remove all of the old grease from each part.

On reassembly, insert 80 g (2.8 oz) of new grease into the 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 40 g (1.4 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.
