Hammer tool greasing 255E
1.2 MANUAL GREASING
Follow the product's greasing instructions and avoid excessive greasing.
Dispose of empty grease containers appropriately.
GREASING INTERVAL
1. Tool shank must be well lubricated before installing tool.
2. 3-5 strokes from grease gun to tool bushings and tool at regular intervals.
3. Adapt interval and amount of grease to wear rate of tool and working
conditions. This can be anything between two hours and daily, depending on
material (rock/concrete) to be broken. See “Recommended greases” on page 38.
Insufficient greasing or improper grease may cause:
■
Abnormal wear of tool bushing and tool
■
Tool breakage
CORRECT GREASING
1. Position the hammer standing upright resting on the tool on firm surface.
2. Stop carrier engine and wait 10 minutes for oil pressure to drop inside hammer.
3. Apply tool grease from grease gun to greasing points marked with the following
sticker.
Note: The hammer must stand upright resting on the tool to ensure that the grease
will penetrate downwards between the tool and the bushing.
