Description	Wear Limit
Wear Sleeve Reverse Dimension	2.205"
Wear Sleeve Discard Dimension	2.165"
NOTE: If no evidence of significant air pressure drop or if wear sleeve is wearing evenly on the top and bottom end, recommendation is to not reverse wear sleeve. Chuck should be replaced when wear transfers to wear sleeve.

Lubrication

The Missile LXQ Series Hammers are precision-made tools and should be treated as such. Only the highest quality lubrication should be used and a constant flow of oil must be maintained at all times. Recommended lubrication amount 1/3 Pint per 100 cfm per hour.

Recommended Grades of Lubricant

ESSO
MATEX
CASTROL
SHELL
MOBILE

AROX EP 150
RDO 302
RD OIL DP 100
AIR TOOL OIL S2 A 320
ALMO NO. 5

Heavy duty oil is recommended for all year-round use, in particular where air supply to the hammer is at high temperature. If lighter grade oil is required due to very low ambient temperatures, amount of oil being used should be increased by 30 percent.
