ToughTek F680e Maintenance Schedule
Maintenance Schedule
- Flush the system.
- Relieve pressure.
- Clean hopper with a scrub pad.
- It is recommended that you clean the outside of the sprayer using a cloth and water.
- Check hoses, tubes and couplings for wear, damage and leaks.
- Tighten all fluid connections before each use.
- Check and replace cam-lock gaskets as needed.
- Check hydraulic oil level and fill as necessary.
- Check compressor oil level and fill as necessary.
- Compressor oil should be replaced after 50 hours (break-in) and every 200 hours after initial oil change.
- If the compressor oil is dark black and shows sediment before the 200 hour time period is complete, replace the oil.
- If the red dot on the compressor sight glass is visible, add oil.
- Inspect hydraulic and fluid lines for leaks.
- Check fluid drain/purge valve for proper operation.
- Clean/flush the valve if necessary.
- Check level of Throat Seal Liquid (TSL) in displacement pump packing nut.
- Fill nut, if necessary.
- Keep TSL in nut to help prevent material buildup on piston rod and premature wear of packings and pump corrosion.
- If operating in an unusually dusty environment, check the filter daily and replace if necessary.
- Remove compressor air filter cover and clean element.
- Replace the element if necessary.
- Check the hydraulic fluid level weekly using a dipstick.
- The fluid level must be between the marks on the dipstick.
- Refill as required with approved hydraulic fluid (see Technical Specifications, in manual).
- If the fluid is dark in color, change the fluid and filter.
- Replace break-in oil in a new unit after the first 250 hours of use or within 3 months, whichever comes first.
- See the table below for recommended frequency of oil change.
- Clean the pre-filter and muffler on the air compressor air relief valve.
- Replace the air relief valve (part 17H606) and muffler (part 120206) if necessary.
- Check belt wear.
- Replace if necessary.
- To prevent rust, never leave water or water-based fluid in the pump overnight.
- Material left on the throat seal can dry out and damage the seal.
- Always stop the pump at the bottom of the stroke to avoid damage to the throat seal.
- Always flush the pump before the fluid dries on the displacement rod.
- First, flush with water, then with oil.
- Relieve the pressure, but leave the oil in the pump to protect the parts from corrosion.
- Exposing the motor and/or control to water can cause damage and possible motor failure.
- Do not store the pump outside.
- Do not spray water directly into the motor fan.
