1. Safety Instructions

In the interest of promoting the safest and most efficient use of the Models CM 7MR, CM 7MRU and
CM 7MC Wall Chasers by all of our customers, it is very important when concluding a sale that the
salesperson carefully ensure that the buyer seriously recognizes the importance of the Handling
Instructions, and fully understands the precautions listed on the Nameplate.

A. 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 using any electric power tool cannot be completely
eliminated. Accordingly, the Handling Instructions list general precautions and suggestions on the use of
electric power tools, and specific precautions and suggestions on the use of the Wall Chasers in order to
enhance the safe and efficient use of the tools by the customer.
Salespersons must be thoroughly familiar with the contents of the Handling Instructions in order to offer
appropriate guidance to customers during sales promotion activities.

B. Caution on name plate

Each tool is provided with a namplate that shows the following basic safety precautions on using the tool.

C. Precautions on usage

Never press the pushing button while the diamond wheel is rotating.
Note that pressing the pushing button during diamond wheel rotation will immediately stop the spindle.
In such case, there is a danger that the M14 bolt for diamond wheel fixation may become loose, resulting in
the diamond wheel unexpectedly flying off and possibly causing serious injury.
