Use And Care Manual
Day-to-Day Guidelines
•  Don’t use extreme force to open or close any Crestline 
Window. It should not be necessary. If operation seems 
overly difficult, the window should be checked carefully 
for a source of interference.
•  Always be sure any Crestline window is fully closed 
before attempting to lock or latch it.
•  Don’t allow children or anyone else to pull, swing or lean 
on open sashes and stabilizer arms.
•  Open and close awning and casement windows only 
from inside using the operator handle designed for these 
purposes.
•  Always apply even pressure to both sides to open or 
close double hung sash, or apply pressure directly in the 
center if need be. Pushing or pulling at double hung 
sash from one side only is inviting problems.
General Recommended Homeowner Care
Double Hung & Slider Windows
•  Keep the tracks on which sash operates and the liner at 
the bottom of the window clean. They should be free of 
trash, dirt, dust and cobwebs. Clean regularly with the 
dusting attachment on a vacuum cleaner.
•   If tracks require lubrication, use only silicone spray, which 
does not attract dirt and dust.
Casement and Awning Windows
As with all moving parts, 
casement and awning window 
hardware will require some 
routine maintenance. The 
frequency of this maintenance 
will depend upon the severity 
of the conditions to which the window and hardware is exposed. 
Windows in homes located near or around salt water will require 
more maintenance than those located inland. Clean window 
frames and sash. Dirt should be wiped clean and brushed away.
Operating Hardware
Clean operating parts of any salt deposits or debris before 
lightly spraying a good quality penetrating lubricant (silicone 
spray, lithium spray, etc.) over the interconnecting points of the 
components, such as: 
•  Crank gears and pocket (Item 1 above)
•  Pivot pins (Items 2 above)
•  Clean and lubricate the sash locks as needed
•  Spray weather stripping with silicone spray only
•  Tighten any loose screws.
Latch Mechanism
Occasionally spray a light coat of a good quality penetrating 
lubricant (silicone spray, lithium spray, etc.) over the internally 
moving components to ensure smooth, easy operation.
Note:  In all instances, avoid applying lithium spray unto the 
weather stripping. It may diminish the effectiveness of 
the weather stripping by making it difficult to achieve 
a tight seal.
