Care and Maintenance
Regular inspection and maintenance are key to preventing
breakdowns and prolonging the life of the equipment.
Keep machine clean and dry to maximize performance and
longevity.
Keep antifreeze in hose and pump in freezing temps or if
idle for more than 2-3 days, see procedure on page 6.
Never let pump run dry!! Pump cavitation can occur in
only a few seconds of low water supply. Ensure adequate
source supply before operating.
Avoid running anything abrasive through pump
which will damage pump components, resulting in total
malfunction or, minimally, loss of pressure capability.
Keep jetter hose away from sharp edges and muffler
• The hot muffler can damage the coating on the hose
making it prone to bursting.
• Sharp edges can scrape, slice and generally damage
hose quickly. While hose is easily replaced, it pays
to take care by buffering sharp edges with tape,
cardboard, or our TigerTail helps protect your hose,
see MyTana.com.
Do not use pulse valve more than necessary.
