200 SERIES TWO-MAN AUGERS
FORM GOM08042004US, VERSION 1.0
English-EN 6
MINIMIZING KICKBACK FROM A DESIGN STANDPOINT
1. Auger features the longest operator handles of any machine of its type
and/or class. Handles are biomechanically positioned to enhance control,
allowing operators to exert "body english" against torque and kickback
forces generated by digging process.
2. Auger features operator handles constructed of non-metallic, composite
material. Material physical characteristics dampen torque and kickback
experienced by operators during digging process.
3. Auger utilizes a twist grip throttle control. Throttle control was selected
over other configurations (for operator handle configuration utilized and
specific digging power) to allow operator to wrap his/her thumb and
forefinger around for effective maximum strength in his/her right hand.
Design provides greater operator machine control when counteracting
torque and kickback forces during digging process.
4. Auger is designed to utilize Brave PN BR10628 (for model BRPA265H) or
PN BR10627 (for model BRPA270H) auger pin for auger bit retention to
transmission driveshaft. Pin is not intended to shear and absorb kickback
related forces when auger bit comes in sudden contact with buried object.
5. Auger pin is utilized for the following reasons:
a. Pin shear would result in extensive physical damage to driveshaft
and auger drive hub.
b. Potentially unknown/large pin quantity could be required to
complete digging of any specific hole even if physical damage to
Auger could be eliminated and/or minimized.
c. Even if replacement auger pin costs are not a factor, resulting
productivity produced by actual process would not be acceptable by
industry and/or social standards for Auger.
d. Given infinite number of potential operators and methods utilized
during digging process, it is impossible to design and supply
specific auger pins to shear at a specific torque value and produce
acceptable operational results for Auger.
e. Given infinite number of potential soil conditions, auger diameter,
auger boring head condition, digging depth, mechanical operating
conditions, operators and operator methods encountered during
digging process, it is impossible to design and supply specific
auger pins to shear at a specific torque value and produce
acceptable operational results for Auger.
6. For comparison purposes, portable electric screwdrivers and drills can
utilize a torque limiting or clutch device to allow drill chuck to slip at a
limited number of specific torque values. For an Auger, such a device
would make the Auger useless due to infinite number of potential
operating configurations required and inability to design specific
components to meet requirements of each operating configuration.
7. Portable screwdrivers and drills are separate tools designed for different
and specific job applications. The drilling process has different
requirements than the fastening process for screwdrivers. Portable
electric screwdriver and drill operational characteristics cannot be
confused and/or substituted for Auger operational characteristics.

WARNING
• An Auger with improperly maintained engine throttle
control will “spin” about its axis when operators lose full
control.
• In event of this occurrence, do not attempt to stop engine
by grasping rotating operator handles.
• DO NOT introduce any foreign object in an attempt to
stop and/or block rotating handles. Instead, allow engine
to exhaust its fuel supply.
• Determine that all components of engine throttle control
assembly allow for proper function before attempting to
further utilize Auger.
