MAINTENANCE INSTRUCTIONS

Your DeckMaster monitor and nozzle should be inspected prior to and after each use to ensure it is in good operating
condition. Periodically, an unanticipated incident occurs where the unit is misused in a manner that is inconsistent with
standard operating practices. A partial list of potential misuses includes:
• Operating above the maximum rated pressure or flow.
• Prolonged exposure to temperatures above 130°F, or below -25°F.
• Operating in a corrosive environment.
• Having the DeckMaster nozzle hit a fixed object during operation or transportation.
• Any other misuse that might be unique to your specific environment.
Also, there are many "tell tale" signs that indicate repair is in order, such as:
• Controls that are either inoperable or difficult to operate.
• Excessive wear
• Poor discharge performance
• Water leaks.
If any of the above situations are encountered, the DeckMaster monitor should be taken out of service, repaired, and
tested by a qualified technician before placing back in service.
Greasing of the elevation and rotation joints is not required under normal operating conditions. Check the motor
operating current periodically to confirm the current is within the Normal Operating Current ranges listed under Product
Ratings. If the current has risen above the normal range, it may be necessary to add additional grease to the joint or to
overhaul the joint to clean and replace the grease. See Table 1 and Table 2 below for grease volumes.
Periodically inspect the condition of the grease in the elevation and rotation joints. See the tables below for
recommendations regarding the condition of the grease.
Do not apply grease more frequently than 1 time per month.
Standard recommended grease is Lubriplate Low Temp. This is an anhydrous calcium, NLGI 1.5 grade lubricant. The
color is white.
For extreme or harsh environments or for continuous duty usage applications, Mobilith SHC460 grease is recommended.
This is a synthetic hydrocarbon grease + lithium complex soap thickener, NLGI 1.5 grade lubricant. DIN 51825: KPHC1-
2N-40. The color is red.
Use of any grease with an NLGI rating higher than 1.5 is not recommended. This may result in excessive operating
currents/stalled motors.
