OPERATING INSTRUCTIONS
3. After light fixtures cool, clean the light lenses using a soft cloth and standard glass cleaner.
After cleaning the mast, if the mast is in extremely harsh environmental conditions, lubricate the
mast with TMD Mast Lubricant (P/N: 900600). TMD Mast Lubricant is specifically formulated for
cold weather use, but is also suitable for year around use. Regular winter maintenance and fre-
quent use of TMD Mast Lubricant should significantly reduce the potential for mast freeze-ups.
To clean and lubricate the mast:
1. While at the 90° position, have one person press the "Mast Up" button to slowly pressurize
the mast just enough to extend the desired mast section. A second person may have to hold
down the larger mast section collars to ensure the desired tube extends. Release "Mast Up"
button as soon as the desired mast section is fully exposed.
2. Wipe down the desired mast section using a non-abrasive cleanser or solvent such as lac-
quer thinner. Do not allow the cleaning fluid or solvent to run down inside the collar.
3. Inject approximately ½ oz. of TMD Mast Lubricant into the weep hole (drain) of the exposed
mast section. The weep holes are located approximately 10" below the collar on each tube
except the top tube.
4. Repeat steps 1-3 for the next larger mast section. Do not lubricate the exterior of the mast.
This will cause the lubricant to attract dust and contaminants from the air.
5. Using the "Mast Down" button, lower the mast to 90°.
6. Wait several minutes to allow the lubricant to settle and spread around the wear ring and seal
at the bottom of each mast section.
7. Using the "Mast Up" button, extend the mast one section at a time. For each section wipe off
any excess lubricant which flows out the weep holes.
