For this project you’ll need safety glasses, gloves, and a Milgard adjustment wrench. Contact Milgard to purchase an adjustment wrench. If window is accessible from the exterior, check window for uneven sightlines or basically if the spacing between window and frame is inconsistent. This will show you how much to adjust your window. Remove screen, then fully open the window. Next, slip the adjustment wrench onto the base of the stub, found between the support arm and the track of the lower hinge. Rotating the wrench away from the lock side of the window will decrease the amount of sash drag, or the part of the window connected to the glass. The maximum sash drag adjustment is reached when the stud flats are parallel to the track. For severe sash drag, a similar procedure can be used on the upper hinge. Upper hinge adjustment is made by rotating the wrench toward the lock side of the window. You’ve reached the maximum adjustment when the stud flats are parallel to the track. Close and open window to ensure you have made the proper adjustments. Go to the exterior window and ensure that the spacing between the window and the frame is consistent around all corners. If sash side spacing is incorrect, then adjust both top and bottom studs in the same direction to move sash left or right. Adjust as needed until spacing is correct. Once the window looks correct, put the screen back into place.
For this project you’ll need safety glasses and gloves. Lithium high pressure grease nlgi number two, number three or number four, mild soap and water solution, silicone spray, and a sponge or lint free cloth.
Begin by wiping exterior with cloth dipped in water and mild non-abrasive soap solution. Tip: test in an inconspicuous area of the window to ensure it won’t damage the window. Take the lint free sponge or microfiber cloth and wipe off non-glass materials to ensure completely dry. Spray window cleaner on glass. Wipe off glass cleaner with soft cloth. Wipe any excess cleaner that might have sprayed onto non glass material. After window is clean remove screen from inside and open window fully. Next use wet sponge or cloth with soapy water and wipe down metal operator, lock bar, and hinge components to remove any dirt or grime. Allow hardware to dry completely. When all components are dry, use silicone to lubricate sliding components and rotating joints. Be careful not to get any lubricant on any wood parts as staining may occur. If some lubricant gets on wood, then promptly wipe off. Apply lithium high pressure grease on operator gear. Check weep holes and make sure they are clear of debris. Open and close window a few times to ensure smooth operation and lubrication. Close window and return screen to complete cleaning and lubrication.
