TENSION CONTROL OF FOCUSING MOVEMENT 

 

The focus tension is easily adjusted by using the Swift adjustment 

wrench.  This wrench fits the tension collar found on the focusing 

controls, between the knob and upright support.  A clockwise turn 

of this collar moves it toward the upright support and increases 

tension, while a counter clockwise turn moves the collar toward the 

knob and decreases tension (see illustration). 

 

CLEANING 

 

Eyepieces should be cleaned as often as necessary to allow 

unobstructed viewing. Clean the eyepieces by brushing away dust 

particles using a soft camel hair brush or with air pressure, then 

moistening the lens by breathing onto it. Wipe the lens carefully 

with quality lens tissue. If dirt or other foreign matter still remains, 

it may be necessary to use water or optical cleaner (eyeglass or 

camera lens). Note: the lens tissue should be moistened, not 

saturated, for cleaning, after which the lens should be dried using a 

quality lens tissue. Painted surfaces should be cleaned with soapy 

water or mild non-abrasive cleaners and a soft cloth.  Do not use 

solvents on painted surfaces. 

COMMON PROBLEMS IN MICROSCOPY 

If you have a problem, you may be able to correct it yourself. Here 
are a few common problems and easy solutions you may want to try 
before calling for service. 
 

CAUTION – Never disassemble mechanical or optical components. 

This servicing should only be done by an authorized Swift technician. 
The Limited Lifetime Warranty will be null and void if the 
mechanical or optical components are disassembled by a non-Swift 
dealer.
