CLEANING
Eyepieces should be cleaned as often as necessary to keep them in good
condition. Clean the eyepieces by brushing away the dirt particles, with
a soft camel-hair brush; then moisten the lens by breathing onto it.
Wipe the lens carefully with a quality lens cleaning tissue. If dirt or
other foreign matter still remains, it may be necessary to use a mild
solvent such as Windex. Note, the lens tissue should be moistened, not
saturated, with Windex for cleaning, which then the lens should be
dried with a lens tissue. Painted surfaces should be cleaned frequently
with mild detergent and a soft cloth.
TROUBLE SHOOTING
A. PROBLEM: The image does not stay in focus.
CORRECTION: Use Swift C-Wrench #MT202 to tighten the tension
collar found on the spindle of the focus controls.
B. PROBLEM: Inability to eliminate double image.
CORRECTION: Try to adjust the interpupillary distance of the
eyepieces. If the problem persists, the objective lenses may
need to be re-aligned. Please contact Swift or your local Swift
authorized repair dealer.
C. PROBLEM: The focus knobs slip at either upper or lower limits of
travel.
CORRECTION: This is normal. A unique slip-clutch is built in to
prevent damage to precision gears. This is activated at both the
upper or lower limits of travel.
