Maintenance Service Interval Maintenance Procedure After the first hour Check the control cable and adjust it if necessary. Check for loose fasteners and tighten them if necessary. After the first 2 hours Change the engine oil.
SPECIFICATIONS & MAINTENANCE Service Interval Service Interval Yearly – Inspect the rotor blades and replace the rotor blades and scraper if necessary. After the first 2 hours yearly. Before each session, inspect the rotor blades for wear. When a rotor blade edge has worn down to the wear indicator hole, replace the rotor blades and the scraper (Fig. 001). A. The wear indicator hole is intact; you do not need to replace the rotor blades. B.
SPECIFICATIONS & MAINTENANCE service classification of SJ, SL, or higher. Use Fig. 003 to select the best oil viscosity for the outdoor temperature range expected. A A B C Fig. 002 A. The oil level is at its maximum B. The oil level is too high, remove oil from the crank case C. The oil level is too low, add oil to the crankcase NOTE You may tip the machine forward (handle up) a little to make adding oil easier. Remember to return the machine to the operating position before checking the oil level.
SPECIFICATIONS & MAINTENANCE Servicing the Spark Plug Service Interval 2 Yearly – Service the spark plug and replace it if necessary. Specifications & Maintenance Use a Toro spark plug (Part No. 119-1961). 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug. 3. Clean around the spark plug. 4. Remove the spark plug from the cylinder head. IMPORTANT Replace a cracked, fouled, or dirty spark plug.
SPECIFICATIONS & MAINTENANCE Replacing the Drive Belt 2. Remove the belt from the rotor pulley (Fig. 006). If drive belt becomes worn, oil-soaked, excessively cracked, frayed, or otherwise damaged, replace the belt. A B C D E F 1. Remove the 4 bolts that hold the drive belt cover (Fig. 005) in place.

Specifications & Maintenance B A Fig. 007 A. Belt Guide B. Engine Pulley NOTE Take care not to distort or damage the belt guide. 6. To install the new drive belt, reverse the steps above.
SPECIFICATIONS & MAINTENANCE Storage Storing the Machine ! WARNING ! • Gasoline fumes are highly flammable, explosive, and dangerous if inhaled. If you store the product in an area with an open flame, the gasoline fumes may ignite and cause an explosion. • Do not store the machine in a house (living area), basement, or any other area where ignition sources may be present, such as hot water and space heaters, clothes dryers, furnaces, and other like appliances.
SPECIFICATIONS & MAINTENANCE 12. Touch up chipped surfaces with paint. Sand affected areas before painting, and use a rust preventative to prevent the metal parts from rusting. 2 13. Tighten any loose fasteners. Repair or replace any damaged parts. Specifications & Maintenance 14. Cover the machine and store it in a clean, dry place out of the reach of children. Allow the engine to cool before storing it in any enclosure.
SPECIFICATIONS & MAINTENANCE Power Clear® 621 (21 Inch Models) Maintenance Recommended Maintenance Schedule(s) NOTE Determine the left and right sides of the machine from the normal operating position. Maintenance Service Interval Maintenance Procedure After the first hour Check the control cable and adjust it if necessary. Check for loose fasteners and tighten them if necessary. After the first 2 hours Change the engine oil.
SPECIFICATIONS & MAINTENANCE Adjusting the Control Cable 1. Slide up the spring cover and unhook the spring from the adjuster link (Fig. 010). 2 Checking the Control Cable Adjusting the Control Cable After the first hour – Check the control cable and adjust it if necessary. Specifications & Maintenance Service Interval C Yearly – Check the control cable and adjust it if necessary. B Move the control bar back toward the handle to remove the slack in the control cable (Fig. 009). D A Fig. 010 A.
SPECIFICATIONS & MAINTENANCE NOTE After extended use, the drive belt may wear and lose its proper belt tension. If the drive belt slips (continuously squeals) under a heavy load,disconnect the spring from the adjustor link and move the upper end of the spring to the hole that is further from the pivot point in the control bar (Fig. 011). Then connect the spring to the adjustor link and adjust the control cable. B A C D Fig. 011 A. B. C. D.
SPECIFICATIONS & MAINTENANCE Changing the Engine Oil Service Interval Service Interval Yearly – Inspect the rotor blades and replace the rotor blades and scraper if necessary. • After the first 2 hours • Yearly Before each session, inspect the rotor blades for wear. When a rotor blade edge has worn down to the wear indicator hole. Replace the rotor blades and the scraper (Fig. 012). Run the engine a few minutes before changing the oil to warm it. Warm oil flows better and carries more contaminants.
SPECIFICATIONS & MAINTENANCE 7. Unscrew the oil fill cap and remove it (Fig. 014). 9. Screw the oil fill cap into the oil fill hole, and hand tighten it securely. A Fig. 014 A. Oil fill cap 8.
