Solution Pump; Solution Pump Clutch; Vacuum Inlet Filter (In Waste Tank); Vacuum Relief Valve - Kärcher PROCHEM Peak GTX2 Operating Instructions Manual

Solution Pump

Refer to the Solution Pump Operation and Service
Manual for specific instructions (P/N 86269900).
1. Check the crankcase oil level daily to assure the
proper level. Use the illustration as a guide when
checking the oil level. If the level has dropped,
check for the source of leakage and repair.
2. Use the provided dipstick. Remove red filler cap
and insert dipstick. Oil level should be between
marks on the dipstick or use a mirror and refer to
the illustration.
3. Change the crankcase oil with Cat Pump
Crankcase Oil (P/N 86189080) after the first 50
hours of operation. Drain and refill the crankcase
oil with Cat Pump Crankcase Oil every 500 hours
thereafter. Oil capacity is approximately 11.8
ounces.
4. Other Cat approved oil equivalents are: Mobil DTE
16, Amoco Rykow 68, and Shell Tellus T68.

Vacuum Relief Valve

The vacuum should be set at 13" Hg. Connect a 50 foot
vacuum hose and a 50 foot solution line to the wand.
Start the truckmount and bring the engine up to
maximum operating speed. Once at maximum speed,
place the wand head to the floor and wet the carpet.
Seal the wand head to the wet floor and check the
vacuum gauge reading. If adjustment is required, shut
the unit down and adjust the vacuum relief valve
locking nut tension. Start your unit and reread the
vacuum gauge. Repeat process until gauge reads 13"
Hg.

Vacuum Pump Drive Belts

To tighten the vacuum pump belts:
1. Loosen the four screws which secure the vacuum
pump to the mounting bracket.
2. Turn the adjusting bolts until the proper belt tension
is achieved (1/2" total deflection in the center of the
belt, halfway between the pulleys).
NOTE: When adjusting belt tension, make certain
that the engine shaft and vacuum pump shaft remain
parallel, and the belt tension is equal throughout the
belt width.
3. After adjusting, re-tighten the four screws which
secure the vacuum pump to the mounting bracket.
Check belt alignment with straight-edge.
4. Check for pulley groove wear, clean belts and
pulley grooves, check for worn belts, proper belt
tension, and pulley alignment after the first 25
hours and then again at 100 hours.
5. Check for belt ride in the groove.
