10.0 Changing the Breaker Tool – [cont’d]
10.3.1 Installing the Breaker Tool - General
The arrangement of front head components and the
procedure for removing and installing the tool is
essentially the same for all models. The tool can be
changed with the breaker on or off the carrier.
The tool is inserted into the open end of the front
head and retained by a pair of large pins, which pass
through slots located on the tool shank. The larger
pins are held captive by smaller pins.
WARNING
Read, understand and follow all safety precautions
described in section 10.1 of this manual before
installing the breaker tool. Incorrect installation
may allow the breaker tool to be driven out of the
front head, possibly causing bodily injury or
property damage.


Screw driver or round push bar

Hammer - Hand sledge

CAUTION
If tool lubrication is provided by an automatic
dispenser, please read carefully. When delivery is
continuous and the output is properly adjusted, the
amount dispensed will be sufficient in volume to
replenish the amount consumed during normal
breaker operations. Any interruptions from normal
grease delivery will require special attention
before the breaker is returned to service.
Interruptions from normal delivery include:

New replacement tool installed

New replacement bushings installed or wiped
clean of grease for purpose of inspection

Any grease line is replaced or added

Operating the grease dispenser beyond the
minimum mark has depleted the reservoir
Prior to insertion, pre-lubricate new tools or tools
wiped clean for inspection. Spread a layer of clean
grease to cover surface of tool shank including the
retainer slots. Further greasing is required after it
is installed. Read and follow instructions for re-
lubrication in Section 10.4. New grease lines must
be Pre-filled. Purge all pockets of air until delivery
is continuous.
Fig. 10-6 Pre-Lube the Tool Shank
10.4 Tool Re-Lubrication – Conventional Method
CAUTION
Crush injury from falling or shifting loads.
All loads must be stable before tool re-
lubrication.
Engage interlock, shut off carrier and
remove key. Follow safety instructions in
the manual provided by the carrier
manufacturer.
Figure 10-7. The breaker must be stood upright with
the tool contacting the ground. Use the carrier to
push down until the tool is seated firmly against the
thrust ring.
