What are the electrical requirements for the G9740 planer?

The G9740 planer operates on 220V or 440V, 3-phase, 60 Hz power. It comes prewired for 220V, drawing 24A at that voltage. At 440V, it draws 12A. The minimum circuit size is 30A at 220V or 15A at 440V. A 4-foot, 10 AWG power cord is included for 220V operation. For 440V conversion, use the P97400120-11 voltage conversion kit.

What kind of motor system does the G9740 use?

The G9740 features three separate 3-phase TEFC induction motors:

• Main motor: 7.5 HP, 3450 RPM, belt drive
• Feed motor: 1 HP, 1145 RPM, chain drive
• Table elevation motor: 1/2 HP, 1725 RPM, chain drive

All motors use shielded, permanently lubricated bearings for long-term reliability.

What is the planing capacity of the G9740?

• Planer size: 20 inches
• Max cut width: 20 inches
• Max cut height: 9 inches
• Min stock length: 10 inches

• Cutterhead diameter: 4-5/8 inches
• Cutterhead speed: 5000 RPM
• Cuts per inch: 84–42
• Cuts per minute: 20,000
• Knife adjustment: Jack screws

What is the difference between the G9740 and G9740Z?

The G9740Z is identical to the G9740 in all specifications except for the cutterhead:

• G9740: Uses four 1/8" thick HSS straight knives
• G9740Z: Comes equipped with a spiral cutterhead

Aside from the cutterhead and some visual differences, the machines are functionally identical.

What are the table and construction details?

• Table bed size: 20-1/8" L × 35-3/8" W × 5" thick
• Table movement range: 1/4" – 9"

• Bed rollers: 2
• Construction:
  • Table: Precision-ground cast iron
  • Body: Cast iron
  • Cutterhead assembly: Steel
  • Infeed roller: Serrated steel
  • Outfeed roller: Smooth steel
• Paint finish: Green powder-coated

What features make the G9740 stand out?

• 4-knife cutterhead (or spiral on G9740Z)
• Twin-V belt drive (main), chain drive (feed & elevation)
• Variable feed speed: 20–40 FPM
• Segmented chip breaker
• Table height lock
