SAFETY INFORMATION 53

Heater/Defroster
― Check operation and blowers for speed control, noise and temperature.
― Inspect heater core for signs of corrosion and/or leakage.
― Check that the defroster blend door is operating correctly and that all ducting
is connected properly.
― Be sure that vents are not obstructed by debris or other objects.
Cab Door Seals and Key Locks
Hollow-core rubber weather seals around some cab doors may lose their
resilience in extremely cold temperatures (i.e., –40°C/–40°F and below).
Under these conditions, it may be necessary to drill holes to penetrate
the hollow core. This allows entrapped air to escape, thereby easing the
opening/closing of cab door(s).
Be sure to keep the key locks clean and dry to prevent occasional winter
freeze-up. Use of antifreeze lubricants is neither required nor recommended.
Outside Mirror Heater
In areas of frequent snowfall and ice, it may be beneficial to install heated
mirrors which will defrost and de-ice cab mirrors. Heated mirrors eliminate the
need to pull off the highway and stand on the roadside to scrape ice and snow
from the mirrors during winter driving conditions. Heated mirrors are available
either cab mounted or fender mounted.
