  Safety Warnings 

1.  Read and understand the entire owner’s 

manual before attempting assembly or 
operation. 

2.  Read and understand the warnings posted 

on the machine and in this manual. Failure 
to comply with all of these warnings may 
cause serious injury. 

3.  Replace the warning labels if they become 

obscured or removed. 

4.  This belt grinder is designed and intended 

for use by properly trained and experienced 
personnel only. If you are not familiar with 
the proper and safe operation of a belt 
grinder, do not use until proper training and 
knowledge have been obtained. 

5.  Do not use this machine for other than its 

intended use. If used for other purposes, 
Walter Meier (Manufacturing), Inc., disclaims 
any real or implied warranty and holds itself 
harmless from any injury that may result 
from that use. 

6.  Always wear approved safety glasses/face 

shields while using this belt grinder. 
(Everyday eyeglasses only have impact 
resistant lenses; they are not safety 
glasses.) Eye wear shall be impact resistant, 
protective safety glasses with side shields 
which comply with ANSI Z87.1 
specifications. 

7.  Before operating this belt grinder, remove 

tie, rings, watches and other jewelry, and roll 
sleeves up past the elbows. Do not wear 
loose clothing, and confine long hair. Non-
slip footwear or anti-skid floor strips are 
recommended. Do not wear gloves or hold 
the work with a rag when grinding. 

8.  Wear ear protectors (plugs or muffs) during 

extended periods of operation. 

9. Some dust created by power sanding, 

sawing, grinding, drilling and other 
construction activities contains chemicals 
known to cause cancer, birth defects or 
other reproductive harm. Some examples of 
these chemicals are: 

 

Lead from lead based paint. 

  Crystalline silica from bricks, cement 

and other masonry products. 

  Arsenic and chromium from chemically 

treated lumber. 

Your risk of exposure varies, depending on 
how often you do this type of work. To 
reduce your exposure to these chemicals, 
work in a well-ventilated area and work with 
approved safety equipment, such as face or 
dust masks that are specifically designed to 
filter out microscopic particles. 

10. Do not operate this machine while tired or 

under the influence of drugs, alcohol or any 
medication. 

11. Make certain switch is in 

OFF

 position 

before connecting machine to power supply. 

12.  Make certain machine is properly grounded. 

13. 

Make all machine adjustments or 
maintenance with machine unplugged from 
power source. 

14.  Remove adjusting keys and wrenches. Form 

a habit of checking to see that keys and 
adjusting wrenches are removed from the 
machine before turning it on.  

15. Keep safety guards in place at all times 

when machine is in use. If removed for 
maintenance purposes, use extreme caution 
and replace the guards immediately after 
maintenance is complete. 

16. The belt grinder should be secured to the 

floor before using. 

17. Check damaged parts. Before further use of 

the machine, a guard or other part that is 
damaged should be carefully checked to 
determine that it will operate properly and 
perform its intended function. Check for 
alignment of moving parts, binding of 
moving parts, breakage of parts, mounting 
and any other conditions that may affect its 
operation. A guard or other part that is 
damaged should be properly repaired or 
replaced. 

18. Provide for adequate space surrounding 

work area and non-glare, overhead lighting. 

19. Keep the floor around the machine clean 

and free of scrap material, oil and grease. 

20. Keep visitors a safe distance from the work 

area. 

Keep children away.

 

21. 

Make your workshop child proof with 
padlocks, master switches or by removing 
starter keys. 

22. Give your work undivided attention. Looking 

around, carrying on a conversation and 
“horse-play” are careless acts that can result 
in serious injury. 

23. Maintain a balanced stance at all times so 

that you do not fall or lean against moving
