PERSONAL SAFETY PRECAUTIONS

2.1

Consider having someone close enough by to come to your aid when you work

near a lead-acid battery.

2.2

2.3

2.4

Have plenty of fresh water and soap nearby in case battery acid contacts your

skin, clothing or eyes.

Wear complete eye and body protection, including safety goggles and

protective clothing. avoid touching your eyes while working near the battery.

If battery acid contacts your skin or clothing, immediately wash the area with

soap and water. If acid enters your eye, immediately ﬂood the eye with cold

running water for at least 10 minutes and get medical attention right away.

2.5

2.6

NEVER smoke or allow a spark or ﬂame in the vicinity of a battery or engine.

Be extra cautious to reduce the risk of dropping a metal tool onto the battery.

It might spark or short-circuit the battery or other electrical part that may cause

an explosion.

2.7

2.8

remove personal metal items such as rings, bracelets, necklaces and watches

when working with a lead-acid battery. a lead-acid battery can produce a short-

circuit current high enough to weld a ring or the like to metal, causing a severe

burn.

2.9

WARNING: Working in the vicinity of a lead acid battery is dangerous.

Batteries generate explosive gases during normal battery operation. For this

reason, it is of utmost importance, if you have any doubt, that each time before

using your tester, you read these instructions very carefully.

2.10 to reduce risk of battery explosion, follow these instructions and those

published by the battery manufacturer and manufacturer of any equipment

you intend to use in the vicinity of the battery. Observe cautionary markings on

these items.

2.11 do not expose the tester to rain or snow.

PREPARING TO TEST

1. Be sure the area around the battery is well ventilated while the battery is

being tested.

2. Clean the battery terminals. Be careful to keep corrosion from coming in

contact with your eyes.

3. Inspect the battery for a cracked or broken case or cover. If the battery is

damaged, do not use the tester.

4. If the battery is not a sealed maintenance free battery, check the level

of each cell and if necessary, add distilled water until the battery acid

reaches the level speciﬁed by the manufacturer. This helps purge

excessive gas from the cells. Do not overﬁll.

5. If it is necessary to remove the battery from the vehicle to test it,

always remove the ground terminal from the battery ﬁrst. Make sure all

accessories in the vehicle are off to ensure you do not cause any arcing.

OPERATING INSTRUCTIONS

5. Make sure the paper comes through the slot in the clear cover before

closing it.

NOTE: this is a thermal printer. If the printer does not print, remove the paper

roll, turn it over and re-insert it.

NOTE: If you have a paper jam, pull the paper out slowly and carefully from

the roll side of the tester and re-insert it properly.

CONNECTING THE TESTER

1. Before you test a battery in a vehicle, turn off the ignition, all accessories

and loads. Close all of the vehicle’s doors and trunk lid.

2. Make sure you have put the six 1.5V aa batteries into the battery

compartment. If the 1.5V aa batteries run out of power, the screen will

show POWer LOW. replace the six 1.5V aa batteries before starting the

test.

NOTE: Nothing will be seen on the display screen until the tester is connected

to a battery.

3. Make sure the battery terminals are clean. use a wire brush to clean them

if necessary. NOte: this tester works best if the battery connectors have

been removed and the battery posts have been cleaned. any corrosion

between the tester clamps and the battery connectors, or between

the battery connectors and the battery posts, will degrade the tester’s

efﬁciency.
