by E-Z Drill based on make and
model of the backhoe
•NOTE: If side bushings are
required, the customer must
supply those.

•Before attaching the air hose to
the drill, turn the air compressor
on and blow air through the hose
to clean out any debris that may
have accumulated inside the
hose. This prevents contaminates
from entering the drill system.
Secure hose before turning air on
to prevent the hose from whipping.

swivel fitting on which to connect
the hose from the air compressor.
