NOTICE TO OPERATORS, MAINTENANCE AND CLEANUP PERSONNEL
REMOVE ANY MALFUNCTIONING TOOL FROM SERVICE
REPORT ANY PROBLEMS TO YOUR SUPERVISOR
1. Disconnect the power supply in accordance with OSHA’s lockout/tagout procedures (29 CFR
1910.147) before making any blade changes.
2. Disconnect the power supply in accordance with OSHA’s lockout/tagout procedures (29 CFR
1910.147) before performing any repair or maintenance.
3. Disconnect the power supply - or have the power supply disconnected - in accordance with OSHA’s
lockout/tagout procedures (29 CFR 1910.147) before performing any cleanup.
4. Disconnect the power supply when the tool is not being used.
5. Always wear eye protection in accordance with OSHA’s eye and face protection requirements (29 CFR
1910.133) when operating the tool.
6. Never put fingers, hands or other parts of the body on the cutting edge or within the cutting path of the
tool.
7. Never allow people to walk in front of the tool during its use.
8. Never allow people to hold / restrain the carcass while operating the tool.
9. Test the tool prior to use or daily. For models with dual anti--tie--down control handles: Depress each
trigger separately and the tool should not start. Depress one trigger, then pause one second and depress
the other trigger and the tool should not start. Repeat this procedure reversing the triggers. Depress
both triggers simultaneously and the tool should start. With the tool running, release one trigger and
the tool should stop. Continue holding the depressed trigger and then depress the other trigger. The
tool should not start. Repeat this procedure holding the other trigger. For models with single trigger:
Depress the trigger and the tool should start. Release the trigger and the tool should stop. If the tool
malfunctions, remove it from service and report or repair it immediately.
10. Test the brake prior to use and daily. After releasing either or both triggers, the tool should stop within
2.5 seconds. If the tool malfunctions, remove it from service and report or repair it immediately.
11. Never depress the trigger(s) unless you want to use or test the tool.
12. Never make modifications or alterations to the tool. Replace any missing or illegible labels.
13. Always use both hands when starting and operating the tool to avoid the risk of possible “kick back”
or “recoil”. Continue holding the tool with both hands until the saw blade comes to a complete stop.
Keep hands clear.
