Minimizing Kickback From Adesign Standpoint - General 240H Operator's Manual

240H ONE MAN HOLE DIGGER
FORM GOM14081201, VERSION 1.1
POSITIONS ENHANCE THE CONTROL OF THE
HOLE DIGGER, REDUCE OPERATOR FATIGUE,
AND INCREASE OVERALL PRODUCTIVITY.
Maintain the operator handle and throttle control
handle grip areas in good condition and free of
moisture, pitch, oil or grease. Wear gloves to
improve your grip. Bent and damaged handles, a
throttle control with a damaged/no grip or handles
without the gripping area material (PVC coating)
aggravate the effects of kickback upon the
operator by limiting control and comfort. Do not
operate the Hole Digger until such damage has
been repaired and/or replaced. Damage to property
and/or personal injury can result.
Always assume that any digging site can include
some form of buried obstruction. Always be
prepared for unexpected auger contact with buried
tree roots, rocks, etc. Under certain operating
conditions, striking a buried obstruction can
produce a severe and/or sudden kickback force to
the hip and/or leg areas. It is possible that this
kickback force can have the magnitude to "throw"
the operator from the Hole Digger. The operator
must maintain physical and mental alertness and
be prepared to accommodate this phenomenon.
Failure to properly accommodate this phenomenon
can result in property damage and/or personal
injury.
IF, DURING THE HOLE DIGGING PROCESS, THE
OPERATOR LOOSES FULL CONTROL OF THE
HOLE DIGGER FOR
FOLLOWING PROCEDURE IS SUGGESTED:
AS A GENERAL RULE, AS SOON AS THE
OPERATOR REALIZES HE IS IN THE PROCESS OF
LOOSING FULL CONTROL OF THE HOLE DIGGER,
HE SHOULD "PUSH" HIMSELF FREE AND CLEAR
FROM THE OPERATOR
ANY REASON, THE
HANDLE. THE
PROCEDURE REQUIRES THE OPERATOR TO
FULLY COMPREHEND THAT HE IS LOOSING
CONTROL OF THE HOLE DIGGER AND TO REACT
ACCORDINGLY WITH
MOVEMENT. IMPROPER REACTIONS TO THIS
PHENOMENON CAN RESULT IN PROPERTY
DAMAGE AND/OR PERSONAL INJURY.
A HOLE DIGGER
MAINTAINED ENGINE THROTTLE CONTROL WILL
"SPIN" ABOUT ITS AXIS WHEN THE OPERATOR
LOOSES FULL CONTROL. IN THE EVENT OF THIS
OCCURRENCE, DO NOT ATTEMPT TO STOP THE
ENGINE BY GRASPING
OPERATOR HANDLE. DO NOT INTRODUCE ANY
FOREIGN OBJECT IN AN ATTEMPT TO STOP
AND/OR BLOCK THE
INSTEAD, ALLOW THE ENGINE TO EXHAUST ITS
FUEL SUPPLY. DETERMINE
COMPONENTS OF THE ENGINE THROTTLE
CONTROL ASSEMBLY ALLOW FOR PROPER
FUNCTION BEFORE ATTEMPTING TO FURTHER
UTILIZE THE HOLE DIGGER.
MINIMIZING KICKBACK
STANDPOINT.
Application: All 240 Series models.
1) The 240H Hole Digger features the widest operator
handle of any machine in its class. The handle is
biomechanically positioned to enhance control by
allowing the operator to exert "body english" against
the torque and kickback generated by the digging
process.
2) The Hole Digger utilizes an antivibration material
(PVC coating) that is applied to the operator handle
during the manufacturing process. This material is
intended to enhance control and help dampen the
torque and kickback experienced by the operator
during the digging process.
3) The Hole Digger utilizes a twist grip throttle control.
This type of throttle control device was selected over
