DANCE WITH OSHA’S LOCKOUT/TAGOUT PROCEDURES

MAINTENANCE.
Refer to pages 4 and 5 for all referenced items.
1 DAILY:
1.1 Check to see that the Model VC is getting
enough lubrication. Each one or two pulls of the
trigger should produce one drop of oil in the
sight dome. If required, adjust the oil flow.
1.2 Make sure that the oil in the lubricator is up to
the full mark. Use USDA approved
Jarvis
Air
Mist Lubricator Oil
.
Do not use mineral oil.
2 WEEKLY:
2.1 Add four to five shots of grease to grease fitting
(item 14). Use USDA approved
Jarvis
1315
White Grease
.
3 WHEN NECESSARY:
Wear cut protective gloves when handling blades.
3.1 Sharpen the blade (item 2) when the blade be-
comes difficult to push into the carcass, or when
the cutting produces contamination.
3.1.1 Place a sharpening stone on the cutting
angle of the blade and activate the tool.
Continue to desired sharpness.
If this action
rolls the cutting edge inward, hold a small
steel on the inside edge of the blade.
3.1.2 Repeat the process until the blade is sharp.
3.1.3 If the angle of the blade becomes too short
or when the cutting edge has excessive
nicks, the blade must be reground.
Do not
heat the cutting edge. Heat will anneal the
material and make it impossible to hold a
sharp edge.
Return to
Jarvis
for regrinding.
