IMPORTANT SAFETY INSTRUCTIONS
WARNING – RISK OF EXPLOSIVE GASES
WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES
GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION. FOR THIS REASON,
IT IS IMPORTANT THAT YOU FOLLOW THESE INSTRUCTIONS EACH TIME YOU USE
THE CHARGER.
To reduce the risk of a battery explosion, follow these instructions and those published
by the manufacturer of the battery and any equipment you intend to use in the vicinity
of the battery. Review the cautionary markings on these products and on the engine.
WARNING: Pursuant to California Proposition
65, this product contains chemicals known to
the State of California to cause cancer and
birth defects or other reproductive harm.
Wash hands after handling.
•Use the battery charger on LEAD-ACID and
AGM-type rechargeable batteries, as used
in automobiles, trucks, tractors, airplanes,
vans, RVs, trolling motors, etc. This charger
is not intended to supply power to low-
voltage electrical systems, other than in a
motor-starting application.
WARNING: Do not use battery charger with
dry cell batteries that are commonly used with
home appliances. These batteries may burst
and cause injury or damage to property.
•Use only attachments recommended or sold
by the battery charger’s manufacturer. Use
of non-recommended attachments may
result in a re, electric shock or injury.
•Locate the battery charger’s power cord so
it cannot be stepped on, tripped over, or
subjected to damage or stress.
•Do not operate the charger if it has received
a sharp blow, been dropped, or otherwise
damaged in any way. Take it to a qualied
professional for inspection and repair.
•Do not disassemble the charger. Take it to a
qualied professional when service or repair
is required.
•Keep out of reach of children.
•To reduce the risk of electric shock, unplug
the charger from the outlet before
attempting any maintenance or cleaning.
•Do not use an extension cord.
•Always charge the battery in a well-
ventilated area
•Do not set the charger on ammable
materials, such as carpeting, upholstery,
paper, cardboard, etc.
WARNING: RISK OF EXPLOSIVE GAS.
•Operate the charger as far away from the
battery as DC charger cables permit.
•Do not expose the charger to rain or snow.
•NEVER charge a frozen battery.
•NEVER set a battery on top of the charger.
•NEVER place the charger directly above a
battery being charged. Gases from the
battery will corrode and damage the charger.
•NEVER touch the battery clips together
when the charger is energized.
•When disconnecting the battery charger, pull
by the plug, not by the cord. Pulling on the
cord may cause damage to the cord or plug.
•Do not operate the charger with damaged
cord or plug.
•NEVER allow battery acid to drip onto the
charger.
•NEVER overcharge a battery.
PERSONAL SAFETY PRECAUTIONS
•Wear complete eye and clothing protection
when working near lead-acid batteries.
Always have someone nearby for help.
•Have plenty of fresh water, soap and baking
soda nearby for use, in case battery acid
contacts your eyes, skin, or clothing. Wash
immediately with soap and water and seek
medical attention.
•If battery acid comes in contact with eyes,
ush eyes immediately for a minimum 10
minutes and get medical attention.
•Neutralize any acid spills thoroughly with
baking soda before attempting to clean up.
•Remove all personal metal items from your
body, such as rings, bracelets, necklaces
and watches. A battery can produce a short
circuit current high enough to weld a ring to
metal, causing a severe burn.
•Never smoke or allow a spark or ame in
the vicinity of the battery or engine. Do not
drop a metal tool onto the battery.
•If it is necessary to remove the battery from
the vehicle to charge it, always remove the
grounded terminal rst.

1. Carefully lay the charger on its front to
prepare for assembly.
2. Assemble the foot (Item 6) using two ¼-20
screws (Item 5) and tighten securely.
3. Attach the two axle brackets (Item 1)
using one 10-32 screw (Item 4) in each.
The brackets should have one end
hooked into the slot in the charger base.
Be careful not to drop the brackets inside
of the charger case. Do not completely
tighten the screws (Item 4) at this time.
4. Slide the axle (Item 2) into the brackets
(Item 1) until centered on the charger.
5. Slide one wheel (Item 3) onto the axle with
the recessed hub facing out, as shown.
6. Insert the pin (Item 8) through the axle hole.
7. Repeat this process for the other wheel
and when both wheels have been pinned
to the axle, nish tightening the two axle
bracket screws (Item 4).
8. Snap the axle caps (Item 7) onto each
wheel to cover the pin and axle.
9. Lift the charger upright so that it rests on
the wheels and foot.
10. Remove the two top side screws (Item 9)
from each side of the charger.
11. Verify that the foam handle grip (Item
12) is on the handle assembly (Item 10).
Install if needed.
12. Insert the berglass clamp rod (Item 11)
into the pierced holes on the inside of the

GROUNDING AND AC POWER CORD CONNECTIONS
This battery charger is for use on a nominal
120 volt circuit and has a grounded plug.
The charger must be grounded, to reduce
the risk of electric shock. The plug must be
plugged into an outlet that is properly
installed and grounded in accordance with
all local codes and ordinances. The plug
pins must t the receptacle (outlet). Do not
use with an ungrounded system.
NOTE: Pursuant to Canadian Regulations,
use of an adapter plug is not allowed in
Canada. Use of an adapter plug in the
United States is not recommended and
should not be used.
USING AN EXTENSION CORD
The use of an extension cord is not
recommended. If you must use an
extension cord, follow these guidelines:
•Pins on plug of extension cord must be the
same number, size, and shape as those of
plug on charger.
•Ensure that the extension cord is properly
wired and in good electrical condition.
•Wire size must be large enough for the AC
ampere rating of charger, as specied below:
Length of cord (feet) 25 50 100 150
AWG* size of cord 16 12 10 8
*AWG-American Wire Gauge
CONTROL PANEL
TIMER
The main function of the timer is to prevent
overcharging, while allowing a battery time
to obtain a satisfactory charge. After the
timer expires, the charger stops charging
your battery. To properly set the timer, you
must know the size of the battery in ampere
hours or reserve capacity in minutes and
the state of charge. It is important that you
determine the appropriate state of charge of
your battery and set the timer accordingly.
HOLD
This position defeats the timer function,
allowing for continuous operation. Use this
position when you want to charge in
automatic mode. DO NOT use this position
when using the 40A manual mode.
AMMETER
The Ammeter indicates the amount of
current, measured in amperes, that is being
drawn by the battery. As a battery takes on
a charge, it draws less current from the
charger. The Start area of the meter
indicates a high rate of current being drawn
from the charger. When cranking an engine,
the starter motor draws up to 300 amps; the
meter needle will be at the extreme right
side of the start area.
The 4 Amp charge rate may indicate some
activity on the meter, although the meter
doesn’t have the resolution to display this
low rate.
VOLTMETER
The Voltmeter indicates the voltage at the
battery terminals. This charger does not
have a load tester, only a voltmeter. Keep in
mind that this reading is only a battery
voltage reading; a false surface charge may
mislead you. We suggest that you turn on
your headlamps for a couple of minutes
before you read the meter. Read a couple of
minutes after you have shut the headlamps
off, and then read the voltage.
YELLOW LED: the battery is charging.
GREEN LED: the battery is fully charged
and the charger is in maintain mode.
CHARGE RATE SELECTOR SWITCH
Use the Charge Rate selector switch to select
the necessary charge rate or Engine Start.

those commonly used in garden tractors,
snowmobiles and motorcycles.
