IMPORTANT SAFETY INFORMATION ENCLOSED.
READ THIS MANUAL BEFORE OPERATING TOOL.
FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY.
Always wear eye protection when operating or
.
performing maintenance on this tool.
Power tools can vibrate in use. Vibration,
repetitive motions, or uncomfortable positions may
be harmful to your hands and arms. Stop using
any tool if discomfort, tingling feeling or pain
.
occurs. Seek medical advice before resuming use.
Keep work area clean. Cluttered areas and benches
invite injuries.
.
Consider work area environment. Don’t expose
power tools and chargers to water. Keep work area
.
well lighted. Do not use tool in presence of flammable liquids or gases.
Keep bystanders away. Do not permit unauthorized
personnel to operate this tool.
Store idle tools. When not in use, tools should be
stored in a dry and secured area.
Don’t force tool. It will do the job better and more
safely at the rate for which it was intended.
.
Use the right tool. Do not force a small tool or
attachment to do the job of a heavy-duty tool.
Don’t use tool for purpose not intended.
.
For example - don’t use screwdriver for a drill.
Dress properly. Do not wear loose clothing or
jewelry. They can be caught in moving parts. Rubber
gloves and non-skid footwear are recommended when
working outdoors. Wear protective hair covering to
contain long hair.
Secure work. Use clamps or a vise to hold work.
Operators often need both hands to perform job
functions.
Don’t overreach. Keep proper footing, balance, and
a firm grip on the tool at all times.
Maintain tools with care. Keep tools sharp and
clean for better and safer performance. Follow
instructions for lubricating and changing accessories.
Inspect tool cords periodically and if damaged, have
them repaired by an authorized service facility. In-
spect extension cords periodically and replace if damaged. Keep handles dry, clean, and free from oil and
grease.
Remove adjusting keys and wrenches. Form habit
of checking to see that keys and adjusting wrenches
are removed from tool before turning it on.
Avoid unintentional starting. Don’t carry tool with
finger on switch.
(continued on page 2)
The use of other than genuine ARO replacement parts may result in safety hazards, decreased tool performance, and
increased maintenance, and may invalidate all warranties.
ARO is not responsible for customer modification of tools for applications on which ARO was not consulted.
Repairs should be made only by authorized trained personnel. Consult your nearest ARO Tool Authorized Servicenter.
It is the responsibility of the employer to place the information in this manual into the hands of the operator.
For parts and service information, contact your local ARO distributor.

(Continued from page I)
Stay alert. Watch what you are doing. Use common
sense. Do not operate tool when you are tired.
Check damaged parts. Before further use of the tool,
a guard or other part that is damaged should be
carefully checked to determine that it will operate
properly and perform its intended function. Check for
alignment of moving parts, binding of moving parts,
breakage of parts, mounting, and any other conditions
that may affect its operation. A guard or other part that
is damaged should be properly repaired or replaced by
an authorized service center unless otherwise indicated
elsewhere in this operation manual.
Have defective switches replaced by an authorized
service center.
Do not use the tool if the switch does not turn it on
and off.
- GROUNDING INSTRUCTIONS
The tool should be grounded while in use to protect the
operator from electric shock. The tool is equipped with a
three-conductor cord and three-prong grounding-type plug
to tit the proper grounding-type receptacle. The green (or
green and yellow) conductor in the cord is the grounding
wire. Never connect the green (or green and yellow) wire
to a live terminal. If your unit is for use on less than 150V,
it has a plug that looks like that shown in Figure A.
An adapter (see Figure B) is available for connecting
Figure A-type plugs to 2-prong receptacles. The green
colored rigid grounding strap must be connected to a
permanent ground such as to a properly grounded outlet
box as shown in figure C.

Extension Cords
Make sure your extension cord is in good condition. When
using an extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized
cord will cause a drop in line voltage resulting in loss of
power and overheating.
Table shows the correct size to use depending on cord
length and nameplate ampere rating. If in doubt, use the
next heavier gage. The smaller gage number, the heavier
the cord.

MAINTENANCE SECTION
TORQUE ADJUSTMENT
To adjust the torque on these screwdrivers, proceed as
follows:
1.
2.
Determine the torque output of the tool by checking a
tightened fastener with a torque wrench.
Increase or decrease the torque output by rotating the
Spring Adjusting Ring (37 or 39). Rotating the Ring
clockwise to a higher number on the Torque Scale
increase torque output while rotating the Ring
counterclockwise to a lower number decreases the
3.
Check the adjustment with a torque wrench. A number
of factors will affect torque output from one job to
another. Final torque adjustment should be made at the
job through a series of gradual increase.. Always start
below the desired torque and work upward.
l
Do not drop or abuse the tool.
.
Whenever a tool is not being used, position the
Power Switch to the “OFF”’ position and unplug the
power cord.

DO NOT ATTEMPT TO REPAIR
THIS TOOL.
The numbers from zero to seven on the Torque
Scale are reference numbers only and are not an
indication of actual torque output.
All repairs and maintenance of this tool and its cord
must be performed by an authorized service center.

EP151ON-J37. Screw the Clutch Housing (12) partially into the Gear Case.
This is a left-hand thread.
At the middle of the Clutch Housing threads, apply
Loctite Threadlocker 3 Bond 1406 (R)* to about
three threads. Push down and rotate the Bit Holder
until it engages the Cam Guide. Hold in place.
Screw the Clutch Housing in completely.
Using an open end torque wrench on the flats of the
Clutch Housing, tighten the Clutch Housing to 28.5
Nm.
Apply grease to both ends of the Clutch Pilot Rod (36
or 38) and insert it into the Gear Case.
For Throttle Lever Start Models, inspect the clearance of the Bit Holder Assembly.
Touch the end of
the Clutch Pilot Rod and push on the Bit Holder Assembly. If the Clutch Pilot Rod is moved by the Bit
Holder at this time, add additional spacers.
Install the Bit Retainer Retaining Ring (l0), sharp
edge side first, into the second groove from the bit
end of the Bit Holder.
Apply grease to the holes of the Bit Holder and insert
the two Bit Retaining Balls (17 or 19) into the holes.
Apply grease to one end of each Clutch Adjusting Pin
(11) and insert the three Pins into the Clutch Housing.
Apply grease to the other end of each Clutch Adjusting Pin and the threads of the Clutch Housing. Screw
the Clutch Adjusting Ring (4) onto the Housing.

Unclamp the Gear Case Jig from the vise and turn it
over to remove the Clutch and Gear Case Assembly.
Hold the Gear Case Shield to keep the Gears in place.
Lift the Motor slightly and slide the Gear Case onto
the Motor with the Ground Screw hole adjacent to the
ground wire.
Attach the ground wire to the Gear Case with the
Ground Screw (74) and Washer (75). Tighten to 4
KG-cm.
Turn the Gear Case until the notch in the Gear Case
matches the tab in the Housing.
Completely insert the ground wire into the groove in
the Housing.
Adjusting the Brake Timing
1. Insert a .65mm thick gauge or pin gauge between the
Pilot Rod Adjusting Screw (55) head and the Shutoff Switch. Push the Bit Holder. The Shut-off
Switch should not click.
2. Insert a .80mm gauge and push the Bit Holder.
The Shut-off Switch should click.
3. Adjust the Pilot Rod Adjusting Screw if necessary
using the two adjusting spanner wrenches.
4. For Throttle Lever Start Models, there is no need
to push the Bit Holder. Slide the gauges between the
Pilot Rod Adjusting Screw and the Throttle Lever
(76).
