Important: Read these instructions carefully. Note the safe operational requirements, warnings and
cautions. Use the tool correctly and with care for the purpose for which it is intended.
Failure to do so may cause damage and/or personal injury and will invalidate the warranty. Please keep
instructions safe for future use.
IMPORTANT SAFETY INFORMATION
•Block drive wheels before use. Set parking brake and put gear selector in neutral for manual
transmission or park for automatic transmission. Risk of sudden vehicle movement!
•Read vehicle's service manual before use.
•Keep away from hot or moving engine parts.
•Use with gasoline engines only. Do not exceed gauge range.
•Make sure all components are properly connected before use.
•Do not use the tester if parts are loose or damaged.
•Wear ANSI-approved safety goggles during use.
•Use the Tester only in well-ventilated areas. A running gasoline engine produces carbon monoxide.
Carbon monoxide is a colorless, odorless, gas that can cause serious injury or death.
•Maintain labels and nameplates on the Compression Tester. These carry important information.
•People with pacemakers should consult their physician(s) before using this product. Electromagnetic
fields in close proximity to a heart pacemaker could cause interference or failure of the pacemaker.
Caution is necessary when near the spark coil or spark plug cables of a running engine.
•The warnings, precautions, and instructions discussed in this manual cannot cover all possible
conditions and situations that may occur. The operator must understand that common sense and
caution are factors, which cannot be built into this product, but must be supplied by the operator.

INSTRUCTIONS
Read the entire “IMPORTANT SAFETY INFORMATION” section at the beginning of this document before
set up or use of this product.
NOTE: Performing a compression test requires the work of two individuals; one person to operate the
vehicle's ignition switch while the other person operates the Compression Tester.
1. Prepare the engine for compression testing by starting the engine and allowing it to warm up to its
normal operating temperature. Then, switch off the ignition. WARNING! Avoid carbon monoxide
poisoning! Never run a gasoline engine in an enclose garage or other contained area.
2. Once the engine has been turned off, make sure that the spark coils are disconnected from vehicle
power supply. Disconnect the power wires from the spark coils. Insulate power wires and route them
away from all metal surfaces.
3. Remove all of the spark plugs. Make note of which spark plug wires go to each spark plug locations.
4. Attach the spark plug thread adapter to connecting hose and the hose to the gauge.
5. Connect the compression tester to the first cylinder of the engine. Crank the engine with starter, with
the gas pedal pressed all the way down.
6. While cranking the engine, observe the gauge. Record the maximum reading.
7. After recording the maximum reading, stop cranking the engine. Then, release the pressure in the
gauge by pressing the pressure release valve.
8. Remove the compression tester from the first engine cylinder. Then repeat steps #5, #6, and #7 for the
remaining engine cylinders.
NOTE: Good engine cylinder compression will be indicated with a high initial reading, and a progressive
build-up to the final maximum reading. Poor engine cylinder compression will be indicated with a low initial
reading, and a much slower build-up to the final maximum reading. The compression readings for all of the
engine cylinders should not vary by more than 10%. Check service manual for acceptable pressure
ranges.
ENVIRONMENTAL PROTECTION
Recycle unwanted materials instead of disposing of them as waste. All tools, accessories and
packaging should be sorted, taken to a recycling centre and disposed of in a manner which is
compatible with the environment.
