7. PRECAUTIONS IN SALES PROMOTION

In the interest of promoting the safest and most efficient use of the Model DH 24PD2 Rotary 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 power 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 Rotary 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. Dust Collecting Equipment
(1) Maintenance of dust collection efficiency
If the dust bag becomes clogged or excessively filled, dust collection efficiency with be reduced. The buyer
should be instructed to clean the dust bag regularly and, for maximum efficiency, to empty the dust bag when
it becomes filled to approximately 40 % of its capacity.
Excessive wear of the passages inside the rubber cap and nozzle seal of the dust collection adapter assembly
will also cause reduced dust collection efficiency. The buyer should be advised to replace the rubber cap and
nozzle seal after approximately 1,000 holes have been drilled. Finally, as moist dust and chips will cause
clogging of the dust collection equipment, the buyer should be advised to use the equipment in dry working
conditions as much as possible.
(2) Applicable materials
The dust collection adapter assembly is designed exclusively for use when drilling in concrete and stone. The
buyer should be instructed not to use the dust collection adapter ass'y when drilling in wood or steel.
