Air Compressor Filter - Mercury 200 Pro XS Operation, Maintenance And Installation Manual

3. Set the spark plug gap. Refer to Specifications.
a. All of the spark plugs should have the gap checked and corrected as
necessary before installation.
b. Measure the gap with a feeler gauge or pin gauge. Never use a
wedge‑type gap checking tool to inspect or to adjust the gap.
c. If an adjustment is necessary, do not pry or apply any force on the
center electrode. This is critical with any type of spark plug that has a
wear surface, such as platinum or iridium added to either the ground
electrode or the center electrode.
d. When it is necessary to widen the gap, use a tool that only pulls back
on the ground electrode without touching the center electrode, the
porcelain, or the wear portion of the ground electrode.
e. When it is necessary to close the gap, gently tap the plug ground
electrode on a hard surface.
4. Before installing spark plugs, clean off any dirt on the spark plug seats.
Install the plugs finger‑tight and then tighten an additional 1/4 turn or
tighten to the specified torque.
