Double-Insulated Appliances
In a double-insulated appliance, two systems of insulation are provided instead of grounding. No grounding means that it is already provided on a double-insulated appliance.
Servicing a double-insulated appliance requires extreme care and knowledge of the system, and should be performed only by qualified service personnel at an authorized Snow Joe® +Sun Joe® dealer. Replacement parts for a double- insulated appliance must be identical to the parts they replace. A double- insulated appliance is marked with the words “Double Insulation” or “Double Insulated.” The symbol (square within a square) may also be marked on the appliance.

DOUBLE-INSULATED: GROUNDING NOT REQUIRED. WHEN SERVICING, USE ONLY IDENTICAL REPLACEMENT PARTS.
This electric scarifier + dethatcher is double-insulated, eliminating the need for a separate grounding system. Use only identical replacement parts. Read the instructions before
servicing double-insulated appliances. Use this electric scarifier + dethatcher only as described in this manual.

Electric Safety

1. Ground fault circuit interrupter (GFCI) protection should be provided on the circuit(s) or outlet(s) to be used for the dethatcher. Receptacles are available having built-in GFCI protection and may be used for this measure of safety.

2. To prevent electric shock, use only with an extension cord suitable for outdoor use, such as SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJOW-A, SJTW-A, or SJTOW-A.
   Before use, check that the extension cord is in good condition. When using an extension cord, make sure to use one heavy enough to carry the current your product
   will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.
   WARNING
   Electric shock may cause SEVERE INJURY or DEATH. Heed these warnings:
   • Do not allow any part of the electric scarifier + dethatcher to make contact with water while it is in operation. If the appliance becomes wet while turned off, wipe dry before starting.
   • Use only a UL-, CSA-, or ETL-rated extension cord for outdoor, all-weather use, such as the Snow Joe® + Sun Joe® SJTW-A 14-gauge 50-foot extension cord with the lighted end (Model PJEXT50-B). Visit sunjoe.com to purchase this extension cord online or, to order by phone, call 1-866-SNOW JOE (1-866-766-9563).

Overload Protection

The overload protection will be activated in the following circumstances:

1. A build-up of scarified material around the cutting device.
2. If the material scarified is larger than the motor capacity.
3. Where there is too much resistance against the cutting

When the circuit breaker has been activated switch off the product and disconnect from the power supply.

Let the product cool down and eliminate the cause before using the product again.

General Operation

WARNING! If the product strikes a foreign object stops the motor. Switch the product off, disconnect it from the power supply, and let it cool down. Inspect the product thoroughly for damage. Has any damage been repaired before restarting?

WARNING! Extensive vibration of the product during operation is an indication of damage. The product should be promptly inspected and repaired.

• Check the machine, its power cord, and plug as well as accessories for damage before each use. Do not use the machine if it is damaged or shows wear.

• Double-check that accessories are properly fixed.

• Push the machine forward by its handle. Keep the handle dry to ensure safe support.

• Ensure that the air vents are always unobstructed and clear. Clean them if necessary with a soft brush. Blocked air vents may lead to overheating and damage to the product.

• Switch the machine off immediately if you are disturbed while working by other people entering the working area. Always let the machine come to a complete stop before putting it down.

• Do not overwork yourself. Take regular breaks to ensure you can concentrate on the work and have full control over the machine.

• Mow the lawn before working and fertilize afterward.

• Make sure that the lawn is clear of stones, sticks, wire, or other objects that could damage the machine or its motor.

• Select the suitable cutting depth for the actual grass

• Do not work with this machine on a wet lawn because it tends to stick to the underbody of the machine, preventing the proper discharge of collected material, and it could also cause you to slip and fall.

• Slowly push the machine forward. Move the machine at an appropriate speed. Do not move it too fast to prevent the discharge from getting blocked and the engine from useless

• Work in slightly overlapping rows. The most effective pattern for scarifying/raking lawns is straight lines along with one of the sides. This will keep the rows even and ensure that all the lawn is scarified/raked without missing any spots (Fig. 11).

• Circle around flower beds. When reaching a flower bed in the middle of the lawn, make a row or two around the circumference of the bed.

• Pay special attention when changing direction.

Scarifying
Consider the weather when scarifying. Scarify the lawn with an increased depth setting during springtime between April and May as the lawn is better able to recover during this season. During a wet summer scarify again in late summer with a decreased depth setting. Do not scarify during periods of hot weather conditions. During a dry rainless summer do not scarify a second time in autumn.

Raking
In order for a healthy lawn to develop in the spring, it is necessary for greater amounts of air to penetrate the area around the roots of the grass. We recommend aerating the lawn every 4 – 6 weeks depending on the state of your lawn.
