SAFETY GUIDELINES
To prevent accidents that could result in serious injury and/or damage to your
vehicle or test equipment, carefully follow these safety rules and test procedures.
SAFETY EQUIPMENT
Fire Extinguisher
Never work on your car without having a suitable
fire extinguisher handy. A 5-lb or larger CO
2
or dry
chemical unit specified for gasoline/chemical/
electrical fires is recommended.
Fireproof Container
Rags and flammable liquids should be stored only
in fireproof, closed metal containers. A gasoline-
soaked rag should be allowed to dry thoroughly
outdoors before being discarded.
Safety Goggles
We recommend wearing safety goggles when
working on your car, to protect your eyes from
battery acid, gasoline, and dust and dirt flying off
moving engine parts.
NOTE:
Never look directly into the carburetor
throat while the engine is cranking or running, as
sudden backfire can cause burns.
LOOSE CLOTHING AND LONG HAIR
(MOVING PARTS)
Be very careful not to get your hands, hair or
clothes near any moving parts such as fan blades,
belts and pulleys or throttle and transmission
linkages. Never wear neckties or loose clothing
when working on your car.
JEWELRY
Never wear wrist watches, rings or other jewelry
when working on your car. You’ll avoid the
possibility of catching on moving parts or causing
an electrical short circuit which could shock or
burn you.
VENTILATION
The carbon monoxide in exhaust gas is highly
toxic. To avoid asphyxiation, always operate vehicle
in a well-ventilated area. If vehicle is in an enclosed
area, exhaust should be routed directly to the
outside via leakproof exhaust hose.
SETTING THE BRAKE
Make sure that your car is in Park or Neutral, and
that the parking brake is firmly set.
NOTE: Some vehicles have an automatic release
on the parking brake when the gear shift lever is
removed from the PARK position. This feature
must be disabled when it is necessary (for
testing) to have the parking brake engaged when
in the DRIVE position. Refer to your vehicle
service manual for more information.
HOT SURFACES
Avoid contact with hot surfaces such as exhaust
manifolds and pipes, mufflers (catalytic
converters), radiator and hoses. Never remove
the radiator cap while the engine is hot, as
escaping coolant under pressure may seriously
burn you.
SMOKING AND OPEN FLAMES
Never smoke while working on your car.
Gasoline vapor is highly flammable, and the gas
formed in a charging battery is explosive.
BATTERY
Do not lay tools or equipment on the battery.
Accidentally grounding the “HOT” battery
terminal can shock or burn you and damage
wiring, the battery or your tools and testers. Be
careful of contact with battery acid. It can burn
holes in your clothing and burn your skin or eyes.
When operating any test instrument from an
auxiliary battery, connect a jumper wire between
the negative terminal of the auxiliary battery and
ground on the vehicle under test. When working
in a garage or other enclosed area, auxiliary
battery should be located at least 18 inches
above the floor to minimize the possibility of
igniting gasoline vapors
HIGH VOLTAGE
High voltage — 30,000 to 50,000 volts — is
present in the ignition coil, distributor cap,
ignition wires and spark plugs. When handling
ignition wires while the engine is running, use
insulated pliers to avoid a shock. While not
lethal, a shock may cause you to jerk involuntarily
and hurt yourself.
JACK
The jack supplied with the vehicle should be
used only for changing wheels. Never crawl
under car or run engine while vehicle is on a jack.
connectors, and hardware, that are not
included with this unit may also be needed.
As the mounting configuration will vary
significantly from vehicle to vehicle, hardware
to mount the tachometer to the vehicle is not
included. Whether you use self tapping or a
machine screw and nut configuration, #8
hardware including flat and lockwashers is
recommended.
CAUTION
This unit is designed for use on twelve
(12) volt negative (-) ground four (4)
cycle automotive type engines. It is not
designed for use on positive (+) ground
electrical systems, two (2) cycle
engines, aircraft or marine applications.
It is compatible with most distributor
equipped and distributorless ignition
systems.
